Leslie, are you using a computer or tablet/phone to come to the site? There are lots of free apps (I use Poto) that allow you to take two pictures and collage them. That's what I do when I list my crosses. Here is an example:
For the listing I would write Daylily, Roman Cohort X Embers of Vesuvius.
If you use a computer you probably have a program on it that would allow you to do the same.
