How many pics can we submit in the ondisplay features?

There are not set rules for the # of pictures. Obviously you want to show off as much detail as possible and give the editor as many choices as possible.
I've seen some with as few as 4 and I am currently editing one that had about 20 submitted. I won't use all 20 but I like the options it gives me.

Main thing is - since its a textless display you want to show off your subject and be able to tell the story with pictures only.

Cool! Thanks!
