My advertising agency started using banner ads on mobile phones is it possible for me to set it up so after someone clicks on the banner ad they can sign up for mobile messaging alerts. Is it possible to broadcast picture messaging?

I use a site called Cellyspace for my business (real estate). Cellyspace has a broadcast feature that lets me create broadcast alerts with pictures and text of new listings. It's really amazing once you get the hang of it. I'd say try it out.
