in my view the very best software for this is ... smart saver pro by ulead.

you can set up a batch very easily and set the resize to a max width and/or height, thus all your pics of whatever size will be resized to the same height or width.

there is a free 30 trial, i don't know if it's been updated recently but my copy is several years old and works like a dream.

imho the compression is better than photoshop/image ready and easier to use. eg better images with smaller file size.
