Trying to turn my personal photography-sharing -tool as SaaS -product

I'm a photographer who does coding for living. I needed simple way to share my shots to my clients. I tried few, some kind of, similar web-apps but they didn't fit for my use, so I wrote my own . Some of my photographer-friends were interested about it and I gave access to few and they liked it.

So, about month ago I had "free"-weekend so I re-built it in form of SaaS and I'm about to release it during this spring. I'm not sure if there is need for this, but I'll do it anyway...

If you have any piece of advice it would be very appreciated.
