Okay, so I've seen people say they can only render because they only have MS Paint. Right, you can't do anything fancy in Paint, but that doesn't mean the only thing it's good for is rendering...
Take a look at this:

Completely made on Windows XP Paint.
And if you can, there are free image editing programs out there such as: Gimp, Paint.net, Photofiltre and more. If you're in one of them situations were you aren't allowed to download anything, there ONLINE image editors available. One of the most famous ones are Pixlr, it can be found here on the site.
So stop whining that you can only make renders.
