Okay - I downloaded your image from your flickr page. I opened it in Photoshop and it was 600 x 600 pixels, but your dpi was 100. It should be 72. Now I'm not sure if that should make a difference or not, but I was able to upload your image. You can see it here http://www.godigitalscrapbooking.com...0b2883&cat=708
It's under my name right now, and I didn't add any information. But if you want to go to the page, right click on it (if you're on a PC, which I assume you are) and save the image to your computer. Then try and re-upload to your gallery. Let me know how that works and I will delete it under my name.
Crossing fingers this works!
