UnderstandingthumbThe role of the filter

Of Security CMSthumbThe filter is a very convenient feature that allows us to directly call the thumbnail version of the image in the template.

The image processing mechanism of AnQi CMS

To answer questions about filenames, we need to understand the overall image processing mechanism of AnQi CMS. According to the instructions in the content settings, AnQi CMS provides a variety of automated functions when processing images:

1. WebP image format conversion:The system supports automatically converting uploaded JPG, PNG, and other image formats to WebP, which can significantly reduce image size, but the change in file format necessarily involves the reconstruction of file content, which usually results in the generation of a new filename.
2. Automatically compress large images:Users can choose to enable the automatic compression of large images and specify the compression width, such as compressing to 800 pixel width.This means that the original image will be processed into a smaller size, and the file content will also change.
3. Thumbnail processing method and size:The system provides various thumbnail generation methods such as "Proportional scaling by the longest side", "Filling by the longest side", and "Trimming by the shortest side", and you can set specific thumbnail sizes.In any way, it involves cropping, scaling, or filling the original image, resulting in a new image file.

Will the original filename of the thumbnail be retained?

Considering the above image processing mechanism, we can draw the conclusion that:thumbThe thumbnail generated by the filter usually does not strictly retain the original file name of the image.

When you upload an image and usethumbWhen the filter is applied, AnQi CMS will perform a series of image processing operations in the background, including but not limited to resizing, format conversion, compression, etc., which will generate aA completely new image file. To distinguish these processed images from the original images and facilitate internal system management (such as recording thumbnail size information, supporting cache updates, etc.), AnLue CMS will allocate an identifier for the generated thumbnails.The new filename and storage path.

For example, the original image may be namedoriginal_photo.jpgAfterthumbAfter the filter is applied, the actual file path of the thumbnail may become/uploads/202309/14/thumb_eba5aa9dc4c45d18.webpor/uploads/202309/14/original_photo_150x150.jpg(The specific naming convention depends on the internal implementation of the system, it usually includes size information or a hash value, and may also be converted to a format).

Although the thumbnail URL displayed on the front-end is different from the original image URL, the Anqi CMS will keep the original image filename and related information in the database, which will not affect your management of the original materials.

What does this mean for content operations?

For daily content operations, it is a standard and reasonable design to not retain the original name of the thumbnail file. This means:

• Thumbnail naming is not required:Automated system processing reduces the繁琐 manual operations.
• Optimize SEO experience:Although the thumbnail filename is different from the original name, search engines pay attention to the image'saltThe attributes and the content of the page they are on. As long as these elements are set properly, the direct impact of changing the thumbnail file name on SEO is negligible.
