As a website manager who deeply understands the operation of security CMS, I know that website content management, especially the effective use of image resources, is crucial for improving user experience and website loading speed.The thumbnail as the first impression of content presentation directly affects the aesthetics and loading efficiency of the page.When there is a need to adjust or optimize the visual design of a website, modifying the thumbnail size is a common operation.This article will detail how to batch regenerate all thumbnails after modifying the thumbnail size in the AnQi CMS, ensuring the consistency of the visual effects of the website content and **practice.
The necessity of adjusting thumbnail size
During the operation of the website, we may need to adjust the thumbnail size due to responsive design requirements, user experience optimization, or new visual standards.Anqi CMS provides flexible thumbnail configuration options, allowing us to set the width, height, and cropping method of thumbnails according to our actual needs.However, merely modifying the backend configuration will not automatically update the existing image thumbnails.This means that if there are thousands of old contents on the website, they will still be displayed using the old thumbnail size, leading to a lack of visual consistency on the website and affecting user experience.Therefore, executing the batch regeneration operation after adjusting the thumbnail settings is an indispensable step.
Modify thumbnail configuration in AnQi CMS
Firstly, we need to adjust the thumbnail size in the AnQi CMS backend management interface. This is usually done in the system's content settings.
Please log in to the AnQi CMS backend and navigate toBackend settingsthen selectContent Settings.
On the 'Content Settings' page, you will see a variety of options for image processing. This includes the two key configurations of 'thumbnail processing method' and 'thumbnail size'.
The "thumbnail processing method" determines how the system processes the original image to fit the target size when generating thumbnails. Safe CMS provides the following methods:
- Scale proportionally by the longest sideThis method will maintain the original aspect ratio of the image and scale the longest side to the specified size, with the other side scaled proportionally.
- Scale proportionally by the longest side with paddingThe image will be resized proportionally to the specified size along the longest edge, and the insufficient part will be filled with a white background.
- [en] : Crop to the shortest edge.The image will be centrally cropped to ensure that the shortest edge fits the specified size perfectly, and the longest edge may be cropped.
Choose the thumbnail processing method that suits your website's display needs.
Then, in the 'Thumbnail Size' input box, you can set the specific width and height of the thumbnails, for example200x150Suggested based on the actual display needs of the front-end page, a reasonable size can effectively reduce the image volume and improve the page loading speed.
After adjusting these dimensions and processing methods, please make sure to click the Save button to apply the new configuration.
Steps to batch regenerate all thumbnails
Once you update the thumbnail configuration, the old thumbnail images will not update automatically.To enable all uploaded content to use the new thumbnail settings, AnQi CMS provides the 'Batch Regenerate Thumbnails' feature.
This feature is located where you just configured.Content Settingsat the bottom of the page.
After you confirm that you have saved the new thumbnail size and processing method, you will see a name calledBatch regenerate thumbnailsThe button. Click this button, and the system will start to traverse all the uploaded images on your website, and generate new thumbnails one by one according to the new size and processing method you have just set.
It is important to note that this process may take some time to complete, the specific duration depends on the number of images on your website and the performance of the server.During the regeneration process, please avoid performing other operations that may affect server performance.
After the batch regeneration is completed, it is recommended that you visit the website's front-end page, clear your browser cache, and check if the thumbnails on different pages are displayed normally according to the new size and style.
Key Considerations
When performing the batch regenerate thumbnails operation, there are some key items that you need to pay attention to:
It is strongly recommended that you perform a comprehensive backup of the website data before performing any important system-level operations, including the database and file system.Although regenerating thumbnails usually does not directly affect the original image file, data backup is always a **practical measure, just in case.
For websites with a large number of images, batch regeneration of thumbnails is a resource-intensive task that may consume a significant amount of server CPU and IO resources in a short period of time.This may cause the website to experience a brief slowdown in access speed or performance during regeneration.Suggest performing this operation during low traffic periods on the website.
The new thumbnail size and processing method may cause the size of the generated thumbnail file to change.If the new size is smaller than the old size, it may save storage space; otherwise, it may increase storage usage.
If the thumbnail on the website front-end does not update immediately after regeneration, this is usually due to website caching or browser caching. You can try clearing the system cache of Anqicms and force refresh the browser (for example, by pressingCtrl+F5orShift+F5），to load the latest image resources.
By following these steps, you can efficiently and accurately manage website thumbnails in the Anqi CMS, ensuring that the website content is always presented to users with a visually appealing effect.
