So I went through all the steps and sections of creating a Homebrew monster. It took a while to write down all of the data and then I got the last step and added what I thought would be small enough photos. They weren't and because the photos were too large I got an error page that said my request was too large.
As a programmer myself I can think of a number of things you can do to solve this bug.
Add some photo validation when the photo is uploaded and disallow the Create Creature button if there isn't a valid photo.
Make the add photos a separate screen so that the creature is created independently of the photo upload call.

bump for this still being an issue
I got around this by adding the images separately. Save the large one first, then go back to edit it and add the small image.
