Have you tried searching for royalty free images on google?
Or you could buy some pro images. I know some sites they cost a few dollars.
Otherwise if you have a good camera, go take some nice images of sunsets or what ever your theme is.
Another idea is you find a artist that will help you, like I've done with my new game.
Which sites do you know where I can buy pro images? I'll check them...
About taking pictures yes that's a good idea. I could do that in the last resort.
Otherwise, anybody knows student artists I could pay for a package contract? Because pro artists or hourly paid aren't possible options for me.
I haven't sent an email to istockphoto yet, haven't had time...
