Need examples for presentation

I am currently enrolled in a nursing program and I will be receiving my pin in December. I am very interested in wound care, and have chosen to do a presentation regarding pediatric wound care. As part of the presentation, we need to use PowerPoint to illustrate key points. I would like to include photos of various pressure ulcers that are commonly found with the pediatric population (as opposed to common adult pressure sores), however, I find myself at a dead end. I have tried as many combinations and versions of pediatric wound care/pressure sores and there doesn't seem to be too many references on the web, and the images found in various articles are limited.

Can anyone point me in a direction? Either book resources I can access, or websites that have pictures...I would really appreciate it!
