Portable Pictures in the pre-alpha stage. This means that the binary files available for download are not feature-complete, and also that they are not officially supported. To download the pre-alpha binary, go to the SourceForge page and click "Download." If you would like the source code for Portable Pictures, you may download it from the SVN repository at http://portablepicture.svn.sourceforge.net. Note that Portable Pictures will not compile "out-of-the-box." It must be properly linked with WxWidgets, Libcurl, and Boost. Opening the included vcproject file in a text editor should give you a decent idea of how to set things up.
