As an experienced CMS website operation personnel for a security company, I am well aware of the importance of website loading speed for user experience and search engine optimization. Images, as an important part of website content, are often the key factors affecting loading speed.The Anqi CMS provides multiple powerful optimization capabilities in the image management function, aimed at helping operation personnel easily enhance website performance.

Optimize website loading speed through the image management function of AnQiCMS

The loading speed of the website directly affects the efficiency of users in obtaining content and their staying time, especially on mobile devices, where users have an extremely low tolerance for slow-loading pages.The image, as the core of visual content, can become a huge bottleneck for website performance if not optimized.Auto CMS has deeply integrated various image optimization strategies to empower website operators to efficiently enhance the loading speed of websites.

1. Utilize the content settings of AnQiCMS for intelligent image processing

The "Content Settings" module of the "Anqi CMS" backend is the core configuration area for image optimization strategies.By reasonable configuration, we can let the system automatically process the images, thereby significantly reducing the file size of the images and improving loading efficiency.

Firstly,Enable WebP image formatIs the primary optimization measure.WebP is a modern image format that can significantly reduce the size of image files while providing the same quality, usually 25-34% smaller than JPEG and 26% smaller than PNG.In the AnQi CMS, once WebP format is enabled, all newly uploaded JPG and PNG images will be automatically converted to WebP format.Batch regenerate thumbnails的功能，能够一键将所有现有图片转换为WebP格式，确保全站图片都享受到WebP带来的加载优势。

Secondly,Automatic compression of large imagesThe function can effectively avoid slow page loading due to uploading large images.We can set a reasonable image width, for example, 800 pixels.When the width of the uploaded image exceeds this set value, the system will automatically resize it proportionally to ensure that the file size is optimized without too much impact on the visual effect.This feature is particularly effective in avoiding performance issues caused by content editors inadvertently uploading oversized images.

In addition,Thumbnail processing and fine control of dimensionsAlso crucial.The "auto" mode provides three thumbnail generation methods: "Scale to fit the longest edgeThumbnail sizeEnsure that the images loaded on the list page, article cards, and other locations are the exact small-size versions required, rather than the original images, significantly reducing unnecessary bandwidth consumption. At the same time, the system also supports settingDefault ThumbnailEnsure that the page has a unified image display even if no specific thumbnail is uploaded, to avoid blank spaces or displaying missing icons.

Finally, for external images that may be referenced in the content,Whether to download remote imagesThe option allows the operator to choose to download external images to the local server.This not only helps to concentrate on managing image resources, but also avoids affecting the website loading speed and stability due to slow or failure of external servers.

English, fine-grained operations and maintenance in picture resource management

The "Image Resource Management" feature of Anqi CMS is not just a simple file browser; it provides image lifecycle management capabilities, which help maintain the tidiness and efficiency of the image library.

In the image resource management interface, we can perform imagesclassificationThis can greatly improve the search and management efficiency for websites with a large number of images.By categorizing images, operators can locate and process specific-purpose images more quickly, such as storing article illustrations, product display images, Banner images, and so on separately.

Batch operations are the key to improving efficiency. Anqi CMS supportsBatch select images for deletion or transfer to a specified categoryThis means that when images are no longer needed or need to be reorganized, multiple images can be processed at once, reducing repetitive labor.

“Image Replacement” feature is especially worth mentioning. When a picture needs to be updated but its URL has been widely referenced, Safe CMS allows usReplace the image file without changing the image URL address.The system will automatically handle the size difference between new and old images and shrink them proportionally according to the compression rules configured in the content settings.This feature is very beneficial for maintaining the images of old articles, updating product images or Banner images, without affecting existing links and SEO performance.

The operation personnel should also check the image resources regularlyFile size and resolutionInformation.Through the image detail page, you can clearly see these key data of each image.Once an image larger than expected is found, manual optimization can be considered, or the system-provided WebP conversion and automatic compression features can be used to process it again.

Three, using template tags to implement on-demand image loading and precise referencing

On the front-end template level, AnQiCMS also provides tag support, allowing images to be presented to users in the most optimized manner.

Among them,Image Lazy LoadingIs the standard practice of modern website optimization. Through the template in the.imgused on tags,lazy="data-src"Property that indicates to the browser to load the image only when it becomes visible to the user.This can significantly reduce the initial loading time for pages with a large number of images, because the browser does not need to load all image resources at once.

In addition, the template should be adapted to specific needs,.Accurately quote different sizes of imagesFor example, a large size may be used on the article detail pageDocument cover first image (Logo)and on the list page, it should refer to the smaller size automatically generated by the systemDocument cover thumbnail (Thumb). The files of AnQi CMS arearchiveDetail/categoryDetail/pageDetailAll tags support direct retrieval of these different image addresses to ensure that the most suitable image is loaded for each scenario, avoiding resource waste.

Through the above multi-level image optimization strategies, Anqi CMS helps website operators manage and optimize image resources from the source to the front-end display, in the process of content creation, editing and publishing, thus building a website with faster loading speed and better user experience.

Common Questions and Answers (FAQ)

1. I have enabled the WebP image format in the background content settings, but why are the old images still in JPG or PNG format on the website front end?autoCMS的WebP启用功能默认只会对新上传The JPG and PNG images are automatically converted.For the images you have uploaded before enabling this feature, the system will not automatically perform batch conversion.Batch regenerate thumbnails”功能。此功能会根据当前设置（包括WebP选项）重新处理所有已上传图片。

2. I set the auto compression of large images to a specified width (e.g., 800px), but some images on the website still look very large, even exceeding 800px. Why is that?Auto compression of large images mainly targetswhen uploadingThe image exceeds the specified width. There may be the following situations:

  • The original width of the image is less than the specified width:If the original width of the image you upload is less than 800px, the system will not enlarge it.
  • Old image has not been reprocessed:Images uploaded before you set or change the compression rules will not be affected by the new rules unless they are reprocessed through the "Batch regenerate thumbnails" feature.
  • The image is an external link embedded directly by the content editor:If the content embeds an external image link and the 'Download remote image' option is not enabled or the link has not been processed by the system, these images are not subject to the background compression rules. Please check the source of the image and the upload time, and use the batch regenerate thumbnails feature if necessary.

3. Is the lazy loading feature of the Anqi CMS automatically implemented? If not, how can I apply it in the template?The lazy loading function of Anqi CMS is not fully automated, it relies onthe cooperation of front-end templates. Although the system may process the image path internally, the final rendering effect needs to be manually modified in your website template.<img>to enable the tag. You need to enable it in the template.srcattribute in the content withdata-src(or any other attribute your front-end lazy loading library requires), and load the corresponding JavaScript lazy loading library on page load. For example, if you are getting image content in the document details tab and want to apply lazy loading to the images within, you can use it like this:{% archiveDetail archiveContent with name="Content" lazy="data-src" %}{{archiveContent|safe}}This will load the contentsrcattribute in the content withdata-srcBy combining it with a frontend JavaScript library, lazy loading can be achieved.
