As I'm recoding my portfolio right now, I thought to myself – how great would it be to have a thumbnail maker tool. Some PHP or Javascript solution to crop images dynamically without the use of Photoshop. I would hate to fire up Photoshop every time I want to upload something. I'm sure you've all been there before. Anyways I landed upon a script that suited my need exactly. The Rectangle Marquee Tool. The tool looks great but was a bit confusing for me to get working and based on the comment for a few others too. Now I've also done some slight PHP modification to get the script working to my needs and generating the correct thumbnails.
See what I'm mumbling on about right here:
