Trouble creating gallery & uploading images

[BayVersBtm]

So I've tried a dozen or more times in the last week to create an image album and upload pics to it, but I constantly run into errors when I do so. Sometimes there's an album there afterward, but it only has a few images out of the set I want to upload (and they're all within the size limits for uploads). If I create the album prior and then try to upload images to it later, I'm able to select it from the list of available galleries, but then I run into a blank pane with the "select an album" line at top, but absolutely nothing in that pane at all.

How do I get this to work right? Is there a limit on what I can currently upload that will expand in time? (And if so, what's up with the loads of errors when uploading any images or trying to select the album to add to?)
