Introduction to SharePoint thumbnails
Sharepoint2010 has a special image library. When you create a new image library, upload a part of the image to it. A row of small images is displayed when you browse this database. When you click an image, a large image is displayed. Do not simply set the size of the Image Tag.
Principles
In fact, when you successfully upload an image in Sharepoint, you actually saved three images to SharePoint. An original image with two thumbnails. How can we refer to the following questions about thumbnails?
When asked about the thumbnail image
I create a picture library picture under my website and upload images to the library. (The IP address here is the IP address of the local area network, and the external hacker cannot only ask for an example)
The source image address is http: // 10.10.11.20/picture/1.jpg.
Thumbnail
1 http: // 10.10.11.20/picture/_ w/1_jpg.jpg
2 http: // 10.10.11.20/picture/_ t/1_jpg.jpg
Add _ t/after file name to add _ JPG
Add _ w/after file name to add _ JPG
Summary
I have learned a little bit about it and I will share it with you. This thumbnail looks better than setting the image size.
