Re-asking the question, I'd like to know how much of a conversion we can show off!
For conversion you NEED one picture of it part way through and may have up to 3 of the finished product.
You can not have more than 3 pictures showing odd your work even if you have multiple images built into one picture.
I personally also make sure i have 2 images of in progress as well.
So in short not counting the pictures of the converting process you may have 3.
