raincoaster--gallery is just the mechanism--you don't have to post a whole bunch at once (at least that's the way it looked to me).
ferndalechickenscratchfever--now that you mention it, I think I was able to find the old template, and go from there, as my first try with the pic was very small (even though it wasn't sized that way initially), though the whole thing was so confusing I'm not clear on the order of things at this point. I just assumed I'd have to play around to figure it out--and hoped there was something I missed with the gallery that you and others would figure out!! And I found no way to preview--sorry I couldn't be more helpful. Not looking forward to trying to use this again.
