Load Images and Scale Images

I looking for it too. I found Photolab and David Batch Processor but I'm not capable to install it. Anyway, to help you in to your search; You looking for a "resize batch script". If you find something, give us some news.

Over at GIMPTalk - http://www.gimptalk.com/forum/script-fu-batch-resize-t9440.html, hello_earth modified redforce's script to batch resize images while maintaining the original aspect ratio. The script is intended to overwrite the original files, so make a copy first and then run the script. I have only used the script under GIMP 2.4.x and 2.6.x; however, there is a script for GIMP 2.2.x. For GIMP 2.4.x and 2.6.x, assuming you installed GIMP in c:\Program Files\GIMP-2.0, if you want all users to be able to use the script, put the script in c:\Program Files\GIMP-2.0\share\gimp\2.0\scripts directory. If you want only a certain user to be able to use the script, put the script in c:\Documents and Settings\username\.gimp-2.4\scripts or c:\Documents and Settings\username\.gimp-2.6\scripts where username is the user. To use in GIMP 2.4.x, click Xtns->Misc->Batch Image Scale By Ratio. To use in GIMP 2.6.x, click File->Create->Misc->Batch Image Scale By Ratio.
