FreeImage is a library project for developers who would like to support popular graphics image formats (PNG, JPEG, TIFF, BMP and others). Some highlights are: extremely simple in use, not limited to the local PC (unique FreeImageIO) and Plugin driven!
A slide show for JPG, GIF, BMP, PNG, TIF, & WMF files; maximizes images without distortion. Folders can be selected at run time, or in advance with arguments or a .picshow file. File name, date of picture, and comment can optionally be shown with image.
Powerful example of a FULLY pluggable multimedia and text editing and review suite - support for an extensive range of file types can be provided for by the use of plugins, and properly-formatted XML modules.
