The Gallery Server Pro Binary Pack adds additional functionality to your gallery, such as thumbnail extraction from videos, TXT, PDF, EPS, and PSD (Photoshop) files. The pack consists of three open source components – GhostScript, ImageMagick, and FFmpeg. They are free and easy to install. The only requirement is that your site must be running in full trust to take advantage of them.
Today I updated the pack to include the latest version of each utility (GhostScript 9.02, ImageMagick 6.70, FFmpeg 0.8). Download it here. To update your existing components, copy the contents of the bin directory in the download to your bin directory, then run the GhostScript setup program. I don’t know if you need to uninstall the previous version of GhostScript first – as a safety precaution you may want to.
