Hi BJ!
You did a good job! I think you mean gumtape though, not cumtape.
It's quite easy to put up pictures, make sure you have a link that goes just to the actual photo, if you use imageshack click the picture until you REALLY only have the picture on a white background. Then just write the link inbetween [ img ] [ /img ] done! (write without spaces)
It's very easy, I know your not very good with stuff like that, but it's really easy and simple.
Great job on making your first completly selfmade costume anyway! It turned out good.

EDIT: Oh and some hosts, like cosplay.com doesn't allow you to link pictures like that, so that might be one of the problems aswell. And I recommed linking directly to the photos and not just to your profile so you have to search, it's alot easier for the ones looking
