Hello, i need a quick intro or some quick code that I can use for this. Currently, images uploaded to the site are big, and of course in some areas I use them as thumbs, and i want them not to be distorted and real thumbs, not resized big images.

I'm totally new to GD Kit, all i know is that it's integrated already. I was wondering if there any simple implementations (not full ones like image.module), but where i can just run at image generation to resize them nicely.

Something like Only local images are allowed.

Thanks, any help or direction is appreciated!
