Search site plugin that includes Cincopa galleries

Hi! I have a website that I manage and I am trying to add a plugin that will allow my customers to search through all components of my site, including the pictures that I uploaded to Cincopa. The search engine is the last thing that I need to add to make it complete. I tried Google custom search & Relevanssi, but they didn’t include my pictures. Does anyone know of a search engine plugin that I can use that would work for what I need?

Also, I’d really prefer to keep all my pics with Cincopa if possible, as I’ve spent more hours than I care to mention perfecting my pictures. However, if there’s no way around it, I will move them if I absolutely have to.
