Fid's dashboard

Hi. First, thank you folks at Synthasite for providing a place for folks like me to have a place to build a site.
I'm trying to build a photography site, where I display thumbnails of my photos, then have them linked to the full size photo. I have about 300+ there now, and I seem to be having two problems. One is, when I drag the "Image" icon into the space where I want it, the window where all my uploaded photos are takes anywhere from 5 - 10 minutes to start loading.
The other problem is, when I click "Update my Site", it sits there for about 5 minutes, then the window pops up that says, "Something has gone wrong". It seems to still send my information, but there seems to be some kind of glitch there. That one is not so crucial, but waiting 5 - 10 minutes to load EACH photo into the given pages will take me years to finish the site. Maybe there's an affiliated site where I can store my photos?
Thanks,
Lee
