SO IRRITATING!!!!!!!

So, as I've mentioned, I've been having a hard time uploading photo's recently. I've had to upload by one or two on the last few posts. Well, it stopped working last night. I had Matt change our browser to firefox, and things are loading faster, but I am still not able to upload pictures!!!!!!! Everyone else seems to be able to. Not sure what the problem is. It might be the server, but if anyone has any ideas to help please let me know!!!!!!! And I'm kind of retarded when it comes to computer stuff.
