proper credits, hints/tips Options

[lovehimvillevalo]

Im not new to CB but I am new to layout design. I have looked through the forum here for answer to some questions before I start designing however there was one that I didn't see an answer for.

Could someone give me some tips/info on the proper ways to credit images, textures, fonts, and whatnot on a layout?

Do I have to put credit on the image I use as a watermark? Or could/do I put it in the layout somewhere or is it just enough to credit in my layout description?

Could I use images from DeviantART provided I have permission from the original artist, as well as give proper credit as to who the artist is and where I got the image?

Any info you can give me would be a great help and greatly appreciated. I would hate to spend all that time on a layout to have it rejected for something as simple as the crediting.

Also, does anyone know any good places to get really good graphics?

Thank you.
