Here's the basic steps that you will need to perform:
1. Transfer the photo (jpg format) from your camera to your computer's hard disk. Sizing of the photo may be an issue.
2. Upload the photo from your computer to some internet server - say one of the photo forums here at YT or some other internet photo hosting service.
3. Link to the internet location of the photo in your post.
I am not familiar with Kodak Easyshare cameras so can't help you with #1. See the camera manual and the software that came with your camera. Once you get past that, I could help you with the rest of it.
