which one is the best plugin to make thumbnails , resize and crop

iimagebrowser

your welcome

and yes it is with 2 i's

I use Photopress....no cropping as far as I know. Just an uploader that automatically makes the thumbs and links them to your post.Brings the full sized image in a new window.
You just have to change the link to point to a gallery if thats what you want
