As an experienced security CMS website operator, I am well aware of the importance of content quality and user experience, and the management and maintenance of images, as an important part of the website content, directly relate to the professionalism and accessibility of the website.About the issue of whether the front-end links of the website will fail after deleting images in AnQiCMS, this is a concern for many operators, and next I will explain it to you in detail.
Image resource management mechanism of AnQiCMS
The AnQi CMS provides comprehensive image resource management functionality, all images uploaded to the system are stored and managed as independent media resources.When you reference an image while editing an article, product, or single page, you are actually referencing the specific URL address of these image resources stored on the server.According to the AnQiCMS documentation, the Image Resource Management Help function page includes all the images uploaded to the website, as well as video resources, and the system allows you to classify, view details, and even replace these images.
In the AnQi CMS backend, you can upload images to the image resource library or directly upload images when editing content. In either case, the system will generate a fixed, accessible URL for these images, such as/uploads/year/month/filename.ext. The usage method of labels in the document also proves this, such asarchiveDetail/categoryDetailandpageDetailLabels such asLogo/Thumb/ImagesDirectly referencing the image URL in the field. This means that the front-end page requests and displays the image through these URL addresses.
The impact of deleting the image on the front-end link
Directly answer your question: After deleting an image in the "Image Resource Management" section of the AnQiCMS backend, the reference link of the image on the website front-end will usually become invalid.
The reason for failure is that when you perform a delete operation, the system will physically remove the image file from the server.Although the HTML code of the front-end page (such as article content, product detail page, category, or single page) still retains the original URL address pointing to this image, but since the corresponding image file does not exist on the server, when the user's browser tries to load the image through this URL, it will receive a '404 Not Found' error response.This will cause the front-end page to fail to display the image, usually manifested as a broken icon or blank area at the image position.
The document mentions thatThis means replacing an image with a new one while keeping the URL path unchanged, ensuring the continuity of references.And deleting is to directly remove the file from the server, losing the foundation of the file as a link target.
Why does the image link fail?
The essence of a failed image link is the failure to locate the resource.AnQiCMS as a content management system, its main responsibility is to manage content and its associated media resources.When content references an image, it stores the path or URL of the image.This URL is the actual address of the image file on the server.Once you delete an image from the background, it is as if you have deleted an entry from an address book and also torn down the building at that address.Although the address may still be recorded elsewhere, nothing can be found there.
Therefore, if the front-end page passes through<img>The tag or other method references a deleted image URL, the browser will attempt to request the resource corresponding to the URL when parsing the HTML code.Due to the absence of this file on the server, the request will naturally fail, causing the image to display abnormally.
How to avoid and handle image link failure
As website operators, we should take positive measures to avoid and handle image link failure issues to maintain good user experience and SEO performance.
Avoiding link failure strategies:
Be cautious when deleting images.Before performing the delete operation, please make sure that the image is still referenced in any content on the website (articles, products, pages, categories, etc.).AnQiCMS currently does not provide a direct function to query the image reference location, so you may need to check manually or confirm multiple times before deletion.
If you just need to update the image content and not remove the image completely, please use the 'Image Replacement' feature first.The document clearly states that "The URL of the image remains unchanged when replacing images", which is an important feature that can effectively avoid link failures due to updates to the image content.
Consider making a backup of important or potentially referenced images before deleting.If subsequent link failure is found, you can re-upload the same name image (if the URL contains the filename), or edit the content to update the image link.
Methods for handling link failure:
First, conduct regular health checks on the website.You can use website crawler tools or SEO tools to detect dead links on a website (including image dead links).The network request in the browser developer tool (F12) will also clearly show the image request for 404 errors.
Once you find that the image link has expired, you need to locate the content page that references the expired link.Then edit the content on the AnQiCMS backend, remove the broken image links, or upload new images and update their references.
If the expired image is a thumbnail or Banner image in the content, you can configure the "default thumbnail" in the "content settings", and when the content does not upload a thumbnail, the system will use the default thumbnail instead.Although this cannot solve all image failure problems, it can serve as a supplementary solution to avoid blank images.
Summary
In AnQiCMS, deleting an image from the image resource management will cause all links referencing the image on the front end to fail.This is because the delete operation physically removes the image file from the server, causing the original URL to not find the corresponding resource.To avoid this situation, website operators should carefully check the references before deleting images and prioritize using the 'image replacement' feature to update the image content rather than deleting it directly.At the same time, regularly checking and correcting broken links on the website is a key link in ensuring the healthy operation of the website.
Frequently Asked Questions (FAQ)
Does AnQiCMS automatically display a default image after the front-end image reference fails on the website? Will not.AnQiCMS does not automatically provide a default image for broken links after image deletion.When the image file is deleted, and the front-end page tries to load the image, the browser will receive a 404 error, usually displaying a broken image icon.You can upload a "default thumbnail" in the "Content Settings" backend, but this only applies to those contents that have not set a thumbnail, and cannot automatically replace all broken image links.
Does AnQiCMS provide a 'Trash Can' feature for deleting images? Based on the provided document information, AnQiCMS explicitly mentioned the "Document Recycling Bin" feature in "Document Management" and stated that the recycling bin is set to retain documents for only 7 days by default.However, the "Image Resource Management" section only mentioned the "delete" operation, but did not mention "move to recycling bin" or the image-specific recycling bin.Therefore, it seems that the deletion of images may be direct and permanent, it is recommended to make a backup before deleting images.
How can I find out which pages reference a picture so that I can safely delete it?The AnQiCMS documentation does not explicitly state that it provides this image reference detection feature.As a website operator, you may need to manually check the following: 1.Search the content of the website (articles, products, pages, etc.) for text containing the image file name; 2.Use external SEO tools or website crawlers to check links; 3.If the image naming convention is followed, one can roughly infer its usage scenario.This is a common pain point in website management, and if the system can provide such a function, it will greatly enhance convenience.
