Wait, you found a waterproof fitness band?!?! Which one? I have the UP 3 because it was originally supposed to be waterproof. It ended up being released as splash proof and slightly disappointing. If it was waterproof, it would be AMAZING!
The app has a camera icon that lets you upload pictures from your phone. Or you can host it on some website like photobucket and they will give you a link to post here.
Edit: I just re-read your post and see you are on your computer so the app option wouldn't work for you.
