I know I can add four free photos per ad, but I was wondering what to do if I have more pictures than that. Four is good, but sometimes it doesn't cover all that I want to cover. For instance, I would like to list multiple puppies or kittens or whatever in one ad. I'd like to list the first puppy with one set of photos and then beneath that, make another post that describes the next puppy in the litter, and so one. With each post in the single thread, I'd like to have four photos. Am I allowed to do this?
