The following review written by one of the Software Informer contributors applies to version 7-SP2
ThumbsPlus SP2 18.104.22.1681 is a graphic file viewer, locator and organizer.
It simplifies the process of finding and maintaining graphics, clip-art files, fonts and animations that you have in your drives, by displaying a thumbnail image of each file.
The program can be used to browse, view, edit, crop, launch external editors, and copy images to the clipboard. Using drag-and-drop you will be able to organize graphics files by moving them to appropriate folders. You can even create a slide show from selected graphics, and install bitmap files as Windows wallpaper.
You can build catalogues of your graphic files by printing the thumbnails.
The program also edits and converts graphics to several formats, one by one or in batch processing.
The program displays a list of folders in the left section of the screen, and the thumbnails of the graphics contained in them on the right. Double clicking on a thumbnail will allow you to edit the graphic associated with it by opening a new window.
You can also access a lot of features right clicking over a thumbnail.
