TIA Lanman I'm not sure how icons are sized. If there is a 'size:40' then you can convert that to any size you want by finding /size: 40/ and replacing that with /size: 50/ any time it occurs in as many files as exist say you have Chapter01 thru Chapter50, then every regexp can be changed to newregexp by 'sed'. Its been a number of years since I have used sed and I dont remember the syntax but it goes something like this: cat /dirpath/* | sed /size: 40/r/size: 50/ tee /newdirpath sed is a stream editor and cat is necessary to stream the data. Do not use the syntax I have shown more may be required or different may be required I just dont remember.

I have several folders of images which need to be resized into several different sizes, so being able to resize recursively through several folders and sub-folders would be handy as well. Imagemagick is made up of a bunch of commands like mogrify and convert (there are more, I think). A lot of times I just use mogrify to resize, but convert will do resizing too. The basic command for resizing is: mogrify -geometry WxH image.png where W is width and H is height (in pixels). Note that this will overwrite the image, so if you want to keep the originals, be sure to copy them. If the aspect ratio doesn't allow you to resize in the dimensions you want, use ! to force the size (distortion will occur), i.e. -geometry 40x35! . Doing this in batch depends on the picture names and whether you've got spaces in the names (or the folders). With no spaces in names or folders, something like for image in `find /path/to/search -type f -iname '*.jpg' -o -iname '*.png'` # (whatever extension(s) you need) do mogrify -geometry 16x16 $image done should do the trick. Find will recurse directories for you; the only issue is if filenames/folders have spaces in them.
