In addition to coding, I know my way around Photoshop and Illustrator.
I can manipulate any images as needed for interface development, plus I can help out with creating website designs, posters, logos, colour correction, and photo clean-up. I'm also useful for creating wireframes, roughs, and comps of the designs that we come up with in our brainstorming sessions.
See examples on the left. Also note that I created all of the images and web designs in the Web section and most of the graphics for the animations in the Video section.
