BIRT is a simple application that allows a large number of images to be resized in one go. It was created in order to facilitate the maintenance of an online photo album where each hi-res photo needs a low-res copy and a thumbnail. License: GNU General Public License (GPL) Changes:
The format (PNG, JPEG, etc.) of images can now be changed as they are resized. Lossless image formats now produce smaller output files. The build system should now work out of the box on standard Linux distributions. The output file name suffix is now inserted in the correct place.
