Uploading Photos -- Problem
I'm in the process of uploading photos for my calendar. I've successfully uploaded some of my photos, and you can see the thumbnail picture of the uploaded photo in the upload sidebar. But there are about ten photos that, after being uploaded, only show the camera/generic image icon in the sidebar, instead of the thumbnail for that photo. I've tried to re-upload some of those, and every time I try to upload them the same thing happens. I've started a support ticket on this, but haven't gotten a response yet. Anyone have any idea why this might be happening and what I can do to fix it? Thanks.
