SpurIT SEO Image Optimizer

PRO- If you have a lot of photos to resize, This is a good app to use. CONS-It does not automatically recognize new photos, from a newly listed item, to resize. You have to manually search for the new listing and manually have it resized. There also isn't a way to sort items from new to old or vise versa, which makes it hard to find a new listing. For the amount of money paid for this app, it should have these important features, especially is someone's store has 500+ items for sale.

A great tool to reduce your images size. It compressed all the images in one go but sadly all the alt descriptions for images were gone meaning that you have to enter them again...
