I have a videogame accessory website with 400+ categories/subcategories. I require image icons for each of these.
You need to find an appropriate image to represent the category (from google or our own site), place it on a blank white background and size it to 155 x 110.
eg if the category is Xbox 360 -> controllers. The image would be an xbox 360 controller on a blank background.
The images need to be clean (no dodgy photoshopping) and it'll help if you have an interest in videogames/consoles.
It's probably a day or two's work for the right person.
