Optimize to file size (image)
Photoshop has a function called optimize to file size which tries to fit an
image to some given file size. Because I need to make sure no images on a
site I'm working on are larger than X KB I need something similar so that
users don't have to worry so much about image file size. Does anyone know
of a way to do this, preferably using ImageMagick or GD?
Doing several calls to ImageMagick with different optimize settings is a not
a good option.

well an arbitrary image will compress without doing at least most of the work
of compressing it.

into 60% jpeg. This keeps me well within the limits. I'm sure there is an
upper bound on how large a jpeg image can become if you know the max
dimension, but I didn't bother to check.
