I will email you the PSD file which has everything on seperate layers so you can change colors or customize it more if you want to, I will also send the transparent PNG. Since you use CS2 you can easily make a brush, but a brush will only be one color, which ever color you choose in the color palette. If you want to use it with all the colors shown you will have to slide the PNG file over your image, resize it then flatten. If you want to save either of the files to a JPEG, just flatten them then SAVE AS JPEG in the drop down menu.
To make a brush in PS2 open your PNG file, desaturate it until there's no color left, then go to brightness/contrast and slide the contrast to the right until all the text is black then go to:
Edit/Define Brush Preset, then a box pops up, name the brush and close out the PNG but DO NOT SAVE or you will save it as a black and white, just close it out. Now go to your brush palette and it will be the last one in there. Pick a color and stamp your logo on an image.
I'm sending both files in a zip folder. What's your email address?

Having faster lenses or fancy camera bodies doesn't make you a better photographer. It just means your crappy images will now be sharper and shot in lower light.
