So I needed some thumbnails. I wanted them created in a subdirectory relative to the location of the image. For instance, if you have dir/filename.jpg it would scale the image down to a specific width/height and drop it into dir/image_thumbs/filename.thumb.jpg. I could not find anything to handle this at the filesystem level, so I had to write one myself… Bash to the rescue! This script requires ImageMagick and a relatively new version of bash due to globstar.
