Uumm... Help!

So I've had an attempt at making my contents page analysis on Prezi... It's proving to be harder than what the teacher had said. Well what I'm mainly having difficulty with is uploading the picture, because at first I had tried this but it was only loading but not showing the picture. Then i told my teacher and he told me to resize the image, I did that. It didn't work, so now I'm getting rather frustrated because i can't seem to carry on because I would need for the image to have fully loaded so I can keep referring back to it. Hopefully the next time I have a go at this it will get better and I can possibly finish off this analysis as soon as possible.
