What is an overlay image?
Sometimes it's fun to grab an image, say from Google and then put your logo on top of it. The G: stands for "Gravity", and the abbreviated values "NorthWest" and "South" and "Center" are used to position the overlayed image. The X and Y values are "offsets" which you can use to tweak the final result.
What's up with this site?
I'm experimenting with ImageMagick and learning how to use it, and I frequently want to create images/logos for sites or blog entries that I wrote without having to remember command-line options.
Can I email you if I found a bug or have an idea?
