Whether it is through the embedded upload function of the content editor, directly inserting the image into the article content, or through the independent "image resource management" module, users can easily upload images to the system.This 'Image Resource Management' module is like a specialized material library, where users can categorize and archive images for easy search and use.Here, you can view the detailed information of each image, including the filename, type, size, resolution, upload time, and storage address.Moreover, the system also supports batch operations, such as batch deletion, batch transfer of images to different categories, and even supports direct replacement of old images without changing the image URL address, which undoubtedly greatly improves efficiency for maintaining the website's image resources and updating images.

To ensure the loading speed and display effect of the front-end page, AnQiCMS has built-in multipleIntelligent processing and optimizationFunction. These settings are all concentrated in the background "Content Settings", allowing administrators to fine-tune according to actual needs:

• Automatic thumbnail generation and processingThe system supports automatic thumbnail generation based on preset rules. The administrator can customize the thumbnail size and choose three processing methods: resize by the longest side proportionally to ensure the complete display of the image content;Pad with the longest edge to center the thumbnail within a fixed size, filling the insufficient part with white;Or trim to the shortest edge, center the image to fit the size.These diversified processing methods can meet the needs of different template designs for image size and display style.If the document does not contain a manually uploaded thumbnail, the system can even intelligently extract the first image from the content as the default thumbnail.
• Image format optimization: AnQiCMS supports automatically converting uploaded JPG, PNG, and other images to more efficient WebP format.The WebP format can significantly reduce the size of images without compromising visual quality, thereby speeding up page loading and enhancing user experience.Administrators can choose to enable this feature as needed and can use the included tools to batch convert existing images.
• Automatically compress large images: To avoid large images from slowing down the page, the system provides a feature to automatically compress large images.Administrators can set a specified width. When the system exceeds this width, it will automatically compress the image, further saving storage space and bandwidth consumption.
• Remote image processingWhen the article content contains images with external links, AnQiCMS provides an option to download remote images to the local.This helps unify image management, avoid the situation where images cannot be displayed due to the failure of external image sources, and also reduce the dependence on external servers.

Frequently Asked Questions (FAQ):

1. Why does the size of the image I upload always look strange or unclear when displayed on the front end?This usually relates to the 'Thumbnail Processing Method' and 'Thumbnail Size' in the AnQiCMS backend 'Content Settings'.The system will automatically generate and process images based on these settings to meet the needs of the front-end template.If the front-end requires images of specific sizes and the backend settings do not match, there may be situations where the size is not suitable or stretched, resulting in blurred images.You can try adjusting these settings, for example, select 'Scale proportionally by the longest side' and set the appropriate size, or use the 'Batch regenerate thumbnails' feature to ensure that the images display correctly according to your frontend design.

2. How does AnQiCMS handle image links from external websites in the article content?AnQiCMS provides the option 'Download remote images' in the 'Content Settings'.If you choose to enable it, the system will automatically download the external images referenced in the article to your server for storage and management.The benefit of doing this is that it avoids the problem of external links failing and images not being displayed, and also unifies the management of image resources on your website server.If you do not want to download external images, you can choose not to enable this feature, but you must bear the risk of external links.

3. Why is the old picture still displayed on the front page even though I replaced the picture on the back-end?This is likely due to browser cache or CDN cache.To speed up access, the browser will cache the static resources of the website (including images).After you update the image, the browser may still display the cached old version.You can try clearing your browser cache or force refresh the page (usually Ctrl+F5 or Shift+F5), sometimes it may also be that the CDN service provider's cache has not been updated in time.If the problem still exists, you can check the background "Image Resource Management" to see if the image has been successfully updated, and confirm that the filenames or URLs of the new and old images are consistent.
