Getting back those cards I've lost... One trade at a time.
First thought it the format of the image. I haven't had issues recently, so I wonder if something changed in the type of file you are trying to post.
No issues lately on this side of the country. Hope you're able to fix the issue. I know that I have different results when I publish on Firefox, compared to Safari. Maybe try a different browser?
I can upload the pictures, but when I click to add the photo nothing happens and then it gets stuck on the upload screen with a small circle in the middle that changes different colors. I have to refresh the whole browser and try again, but no dice. I'm still using JPEG too... no change there and I'm not sure I have another browser on this laptop to choose from. We only use explorer. I guess i'll try from another computer at some point.
