I have amassed quite a collection of digital photos - ranging in size/quality from simple snapshots, to 40MB RAW and TIFF files. I'm looking to give a digital photo frame as a present pre-loaded with a bunch of photos. The resolution of the frame is 800x600 so I'd like to fill a directory with the photos I desire (some much larger than the 800x600 resolution) and run a batch tool of sorts to convert them all to JPEG in the desired size.
I tried searching the web and found many windows utilities (which I refuse to use!) but never saw a good linux alternative.
I'm sure one exists, if you have a suggestion I'm all ears (Command line utilities are fine too)
So let's hear from the photography experts or web masters out there - how do you convert a bunch of high res photos to a common size for web galleries, photo frames, etc.
