Experiencing Site Glitches

I'm hoping this is the right place to post this as I don't come to the forums very often. F
or a few hours, I've been noticing a few glitches over the site.
The first is when I'm adding/rearranging items in my lists, the images either don't show up at all, or their thumbnails just say "Upload An Image" when there was a picture there just yesterday.
The second is a rating issue, when I click to add stars to a person/movie/whatever, they don't show up, like I never clicked. So I try & try again but still nothing.
The third & final is the site seems to be going somewhat slow. It's not just my computer, as no other sites are acting slow for me at the moment.
I really don't think this is just me; I haven't changed any settings in my computer since I last logged on. So any help would be appreciated.

I am working on fixing the image errors. For the other issues I think the site was just running slow so was not registering the ratings, it seems to be ok now.
