P4Web can display image thumbnails for depot files. All thumbnails are based on file revisions in the depot—P4Web does not display thumbnails of files in the workspace. Note the following:

• The p4thumb daemon must be running. This daemon generates thumbnails for image files stored in thedepot. For details, refer to the p4thumb release notes on the Perforce technical documentation web page.
• Thumbnails are display only for supported image file formats. Supported formats are listed in the p4thumb release notes.
• Thumbnails are displayed for the last-synced revision of the image files. If you modified the image files after you synced them, your modifications are not displayed in the thumbnails shown by P4Web. For files that have not been synced, the thumbnail displays the head revision.

To display an image in your browser, click its thumbnail. To display its revision history, click its filename. When you display the revision history, P4Web displays a large thumbnail of the image file.
