In the meantime, another way to check this out would be to try and upload the same file that I am going to upload here.
In my daytime job, my students are currently working on a state project and we have visited the official website of each of the 50 United States.
Let's use the state of Wyoming for this example. Their official state website is
http://www.wyo.gov
Under the About Wyoming header, there is a Facts and Symbols tab. Click that (or, here is the direct link:
http://www.wyo.gov/about-wyoming/wyoming-facts-and-symbols )
Try downloading the Wyoming State Flag. (To download this image, point your mouse on top of the image, then right mouse click. One of the options you
should then see will be Save Image (I am assuming you are a Windows user....). Save the image to your desktop (for easy later location and cleanup after you attempt to upload).
Then come back here and in a reply to this thread, see if you can upload that photo. It should look like this:

Here is some more info on that file and a screen shot of where to find it - and yes, I am a Mac user!

At any rate, if you can upload a small file like this - one we know that works - then that would suggest something about the upload you are attempting still is not within TUG's allowable parameters.
Good luck on this!
