In Anqi CMS, when managing content, we often encounter various fields related to images, among whicharchiveDetailthe label underLogoandThumbFields are often confusing for some new users. They all represent images, but there are very clear and practical differences in their use and system processing.Understanding these differences can help us better plan image content, improve website loading speed, and enhance user experience.

Logofield: the face of the content

When we go througharchiveDetailwhen the label calls the document detail data,LogoThe field is usually understood as the 'cover image' or 'main visual' of the content.It carries the core visual information of the document or product, and is the image we expect to be most prominent and clear on the page.

In practical applications,LogoThe field often returns the original image you uploaded (or a version compressed by the system), which is usually large in size, retains complete details, and is suitable for the top of the article detail page, the large image display area on the product page, or as the main thumbnail when sharing on social media.It aims for visual impact and content representation, which is the first thing users pay attention to when browsing content.

For example, when you write an article about a new product, the product image is its core, and you want this image to be presented in a larger size and high definition on the article detail page, then you upload and specify it asLogoThe image can well meet this need.

ThumbField: efficient thumbnail preview

withLogoOn the other hand, it isThumbField, as the name implies, it represents the "thumbnail" of the document.ThumbThe birth of the field is more to solve the demand for image efficiency in scenarios such as content list pages and related recommendation areas.In these scenarios, we need to display multiple images at the same time, and we hope the page can load quickly, reducing the user's waiting time.

Anqi CMS is processingThumbAt the same time, it provides very fine control. You can uniformly configure the thumbnail processing method and size of the website in the "Content Settings" background. This means that when you callThumbWhen the field is specified, the system will automatically resize, crop, or pad the original image according to these preset rules, generating a thumbnail version with a smaller size and better file volume.

It is smarter that if you do not have a specialThumbUpload image, but if the document content contains images, Anqi CMS will automatically extract the first image in the content as the source of the thumbnail and generate it according to the preset rulesThumbThis kind of automation greatly reduces the workload of content editing, while ensuring the performance advantage of the website in terms of image loading.

For example, on the article list page, each article needs a cover image to attract users to click. If you directly useLogoa large image, it may cause the page to load slowly. At this time,ThumbA field can be put to good use, it provides a standardized, optimized thumbnail, which can display the overview of the content and ensure the smooth loading of the page.
