I use Picnik, so it's nothing fancy. But I'm running out of picture to edit and I'm on winter break so I'm bored! I don't usually do words, but I like doing show names, so if your horse has one and you wanted it included please say so. They're not great, but I just want some practice. Also, the clearer the picture, the more I can do with it. If you send two or three pictures so I have a few to choose from that'd be great.
Here are some examples... I also have more examples at this link if you want to see them. Horse Edits pictures from horses photos on webshots
