Glass Tile - photo pendants

I ordered up some of those 1x1 glass tiles - will make some pendants out
of my art. I don't have Adobe Photoshop, so trying to get the images
to be 1x1" took hours! I'm sure there is a simple way, but never had
to edit a photo to be so small. Figured it would be a nice way
to offer my artwork at a very affordable price. I will print them
out on photo paper. The little images look good. I added some contrast
and sharpened the image. Can't wait to get the glass tiles. Couldn't find

them at any local craft store. Had to order them.
