Visual Essays?? Need Help!

Okay, I have to make a visual essay for my English portfolio. This portfolio is a final project and is worth a huge portion of our mark. One of the required pieces of work is a visual essay which we have to complete on our time.
I've never done a visual essay in my life, and I desperately need some help. Its due soon. Any suggestions of any kind would be appreciated so much!

You could probably set up some pictures on a piece of Impraboard (not sure what you call it) with captions. One tip is to make sure that it's neat, like everything else. Decorations might help as well. Basically, I think you should just get pictures, captions, and pieces of information printed and stick them on the board.

Okay, thank you!
I was starting to get worried because nobody else I've talked to has done one or knows what they are. Yet, we're supposed to know this, according to my English teacher. Seems like a dumb thing to do for English class though.
