I came across this product on one of the many sites i read, and i have to say it very different to anything else i have seen.

http://www.easyimg.com/

What this basically does is gives the end user a way to instantly change images on their site without using a graphics program! :confused:
The way in which it work is by using variables in the url when the browser fetches the image.
You can change the colour, size, add a gradient, add text, change the font, add a border etc
I have to say it's very intuitive
