Adding Pictures to Gallery Listings

I am having trouble uploading pictures to my gallery listings. The images are the correct size and I get the message that the image was successfully uploaded but then there is no picture when you look at the listing either in my gallery or on my account page. Is anyone else having this problem? I just started using Windows 8, could that be it?

I've had that happen to me a couple of times, when I would try to add a new cel. I would hit the upload and no image would appear. Not sure what the issue is but I kinda got through it by being persistent. I would try it a couple of times and eventually the image would load correctly, or just leave the page for a few an then go back to it and it would suddenly work. Not sure if this helps, but that's the only thing I can think of.

Thank you rinoa for the suggestion. I will keep trying.

Still no luck :( It works on my father's computer just fine too which frustrates me even more.
