The core of ensuring consistency in document image display: default thumbnail settings

In the daily operation of websites, we publish a large amount of content, and it is inevitable that some documents do not have a dedicated thumbnail uploaded, or that the content does not contain any images.If there is no unified default image to fill, blank spaces or style disarray may appear on the page, which undoubtedly will damage the overall image of the website.The default thumbnail feature of AnQi CMS is designed to solve this pain point.Through reasonable settings, you can ensure that all documents without specific thumbnails automatically use a preset image for display, thus ensuring visual consistency and professionalism.

Understanding thumbnail processing rules and dimensions

On the “Content Settings” page, you will find several key configurations that together determine the generation and display of thumbnails on the website.

The first is 'thumbnail processing method'. The CMS provides three main thumbnail generation strategies to meet different design requirements:

  • Scale proportionally by the longest sideThis method ensures that all sides of the image are fully displayed.The width or height of the thumbnail will be fixed on one side, and the other side will be scaled proportionally based on the original image's aspect ratio.This means that the thumbnail generated may not strictly match the size you set, but the image content will be complete.
  • Scale proportionally by the longest side with paddingIf you want the thumbnail width and height to be strictly fixed without cropping the image content, this option is very suitable.The image will be centered within the specified size box, and the insufficient part will be filled with white (or the background color set in your template).
  • [en] : Crop to the shortest edge.This method trims the image based on the center, ensuring that the thumbnail fills the specified size, but may cut off some of the original image content at the edges.This is a good choice if your design requires strict image ratios and fill, and you can accept some degree of cropping.

The following is the 'Thumbnail Size' setting.Here, you can enter the expected thumbnail width and height according to the design requirements of the website frontend template (for example, 200x150).Accurately setting these dimensions is crucial for achieving a uniform layout on the page.

Set your website's default thumbnail

After you understand the handling and size of thumbnails, you can set that 'universal' default thumbnail.On the "Content SettingsClick the upload button, you can select an image from the image library that matches the style and theme of your website, or upload a brand new image.This image will serve as a backup image for all documents that do not have a thumbnail specified separately.This means that even if the content publisher forgets to upload a thumbnail, or the article itself does not contain any images, the website will not appear blank or display any missing placeholders. Instead, it will uniformly display the default image you have preset, greatly enhancing the visual consistency of the website.

Batch processing and content consistency maintenance

The website may adjust the thumbnail size or processing method during long-term operation, at which point the existing thumbnails may not conform to the new specifications.To avoid the tedious work of manually adjusting one by one, Anqi CMS provides a very practical feature: 'Batch Regenerate Thumbnails'.When you modify the 'thumbnail size' or 'thumbnail processing method', click this feature, the system will automatically traverse all the uploaded images and regenerate the thumbnails according to the new settings.This ensures that you can maintain consistency in all document images quickly and efficiently even when the website design style or display requirements change.

Through these detailed configurations, the security CMS enables website operators to easily control the display effects of document images. Whether it is new content or historical data, it can maintain a high degree of visual consistency, providing users with a more professional and beautiful browsing experience.
