This forum has a 1000kb limit for picture uploads and finding a solution to reduce files to this size wasn't as easy as I'd have expected so I wrote a little BASH script that iterates through various sizes and keeps the largest one closest to 1000kb. It requires ImageMagick (convert) and needs to be run as follows:

./resize.sh myfile.jpg

It will output myfile_sm.jpg which should be as close to 1000kb as possible

And what's exactly the benefit of script over using ImageMagick straight?

Because I couldn't get IM to output a JPEG that was as close to 1 megabyte as possible. If you know a way then please share.
