hi,
i'm new to stockfotgrafy and the rights that belongs to it. i want to know if it is legal in general to sell pictures that were made out of "free photoshop brushes". you know i mean these floral and fractal brushes an kind like that. often the author writes a comment like the brushes would be free for personal and commercial use and he just wanna be linked beside.
for instance i had found a gratis brush pack on a website that sells royality free vector brushes. below the pack it concerns the following text:

"You can use our products like a printed product and it is good to use our designs as many times for Royalty free license.. You can use our designs your personal designs or your client commercial projects.Royalty-Free concept means that you can buy one particular clipart and after you pay for it you can use that clipart as many times as you like, with some minor restrictions. This mean that you are NOT ALLOWED to resell, share with your friends, give away, repackage or redistribute our clipart in any way."

do you've got any suggestions?
