Is it possible to post photos of previous clients to a new profile?

I am new to http://Rover.com, but am an experienced dog-sitter. I'd like to publish some photos of previous clients to make my profile a bit more attractive to prospective customers, but it looks like the only photos I can add are of a personal pet, and I don't currently have any dogs of my own. I read in the knowledgebase that I can publish photos of new clients during their stay, but is there really no way to just post a few pics of my home and perhaps a shot or two of my past clients at the dog park?
