Adobe Photoshop LE question?

Open your image then go to your Layer menu. Select New Layer, and leave all the other setting alone.
After that, go to your paint bucket tool, pick the colour that you want and fill your image with that ink. You should now have a solid colour image.
Next step... go to your rectangular area selection tool, which should be the first icon on top left. Click in any corner about where you want the thickness to be, then while holding the left mouse key down drag until you make a nice rectangle that will look like the frame you want. When at that point release the mouse key, then Apple+X on a mac, or Control+X on a PC.
