In website content operation, images are undoubtedly an important element to attract visitors, and the loading speed and display effect of images directly affect user experience.In order to optimize website performance, using thumbnails properly becomes particularly crucial.Many websites' systems will dynamically generate or call different-sized images by appending parameters to the image address.How does Anqi CMS handle this aspect?Does it support automatically appending a thumbnail parameter to the image address to display?
After understanding the function mechanism of Anqi CMS, we can clearly say that Anqi CMS adopts a more systematic and efficient strategy in dealing with image thumbnails, butThe method is not to display thumbnails by dynamically attaching thumbnail parameters to the original image address.
The focus of AnQi CMS is to provide a comprehensive thumbnail generation, management, and calling mechanism, rather than relying on the client or server to parse parameters dynamically and adjust images with each request. This means that after you upload an image, if the thumbnail feature is enabled and the relevant configuration is in place, AnQi CMS will generate thumbnails according to the preset rules,Generate or process a standalone thumbnail file and provide a dedicated access address for this thumbnail.
This processing method has several significant advantages: Firstly, it greatly reduces the dynamic processing burden on the server during each image request, as thumbnails have been pre-generated.Next, it ensures consistency and high quality of thumbnails during display, avoiding display issues that may arise due to improper dynamic cropping parameters. Moreover, this independent file method is also more conducive to CDN distribution and browser caching, further enhancing the website's loading speed.
In the background management of Anqi CMS, we can see a series of refined options related to thumbnails.For example, in the 'Content Settings', you can define the 'thumbnail processing method' (such as proportional scaling by the longest side, padding by the longest side, or cropping by the shortest side), set the 'thumbnail size', even specify a 'default thumbnail', and perform the 'batch regenerate thumbnails' operation.These features all indicate that the security CMS has a centralized and intelligent management of thumbnails.
How to call a thumbnail in a template?
The AutoCMS provides very intuitive and convenient template tags and filters to call these pre-generated thumbnails.
Call directly through the content field:For articles, products, single pages, and other content, Anqi CMS will directly provide a field named
Thumb(Thumbnail). For example, on the document detail page, you can{% archiveDetail with name="Thumb" %}Such a label, directly obtain the thumbnail address of the document. Similarly, category and single page details also support obtaining thumbnails throughThumbfields.Use
thumbFilter processing:If you want to generate thumbnails for the image addresses referenced at other positions in the template (for example, throughLogothe original large image address obtained from the field) as well, safe CMS provides athumbFilter. You just need to pass the image address to this filter, and it will return the thumbnail address of the corresponding size. For example:{{ item.Logo|thumb }}This allows you to flexibly convert any image into the thumbnail form preset by the system.
These tags and filters directly return the processed, appropriately sized thumbnail URLs, which we can use directly.<img>TagssrcProperties, to achieve fast and efficient image loading.
In summary, the Anqi CMS indeed provides very comprehensive support for the display of thumbnail images on website pictures, but its implementation is not achieved by dynamically appending parameters to the original image address.It focuses more on providing a stable, efficient built-in thumbnail management and calling mechanism, optimizing image loading performance and user experience by generating independent thumbnail files.
Common Questions (FAQ)
1. How will the Safe CMS handle it if I do not upload a thumbnail when releasing the document?The AnQi CMS is very intelligent.If you do not manually upload a thumbnail when adding a document, but the document content contains images, the system will automatically extract the first image in the document content as the thumbnail for the document.If the document content does not have any images, and you have set the "default thumbnail" in the background, the system will use the default thumbnail you specified to display in place.
2. Where can I set the size and processing method of the thumbnail?You can find the 'Content Settings' option under the 'Background Settings' menu in the Anqi CMS background.Here, you can flexibly configure the 'processing method' (such as aspect ratio scaling, padding, cropping) and 'thumbnail size' of thumbnails according to the actual needs of the website.These settings will be applied to all newly uploaded images and scenarios that require thumbnail generation.
3. The thumbnail generated by Anqi CMS is a new image file or a dynamic version of the original image?When Anqi CMS processes thumbnails, it will generate them according to your configurationNew, independent image file.These thumbnail files have their own storage path and URL, which is different from the original large image address.This method helps to manage image resources more effectively, improve loading speed, and facilitate access to services such as CDN.
