Images Of A Good Mammagram I Need A (free) Program That Will Enable Me To Resize And Edit Multiple Images At Once, Any Good Ones?

I need a (free) program that will enable me to resize and edit multiple images at once, any good ones? - images of a good mammagram

I did not walk a lot of eBay auctions, and through, improve and modify each individual image, one after another, first a long time. I wonder whether image editors are well able to do this for me.

I hear Photoshop is capable, but incredibly expensive.

Is there a program for image editing, can it? Thank you!
