ok, bear with me please, this could be long and confusing :) let me just start by saying i'm glad you're so helpful and quick to respond and patient!
so i'm still having some problems. It seems as though i've gotten the gallery format to work, (for some posts that is) but then all of a sudden, when i continued as I had been doing, only one of the pictures showed up as round, and actually before, they were all showing up as round and then underneath the title of the post as the standard rectangle...i deleted them from the post (so they essentially did not show up on the editing page) which deleted the rectangle pictures i didn't want, and somehow maintained the circular ones (even though the image doesn't appear on the edit post page..i'm not sure if that's correct or not, but i'll take it!)
but now, as I said, all of a sudden they same problem i was having before started happening, and only one image shows up as a circle, and the rest as the standard rectangle. I have no idea what i did....
i'm sending you the link (the address needs to be worked out, but that's a different story, don't worry, i've got someone helping me with that, it will not be the permanent link to the page), and actually, just now checking to make sure it works, i tried opening it with firefox (i'm using google chrome) and none of the images are circles, but oh well!
let me know if you think of anything! thanks!
