I can't to post up my duck from this past hunt
It could be that the image is too large. Try opening the photo in "Paint" or some other similar program and shrink it down and save it. Then try to up-load it again. Or, the easier way is to open a photobucket or flicker account. These are free. You can up-load on to one of these sites, then copy the link address for the photo and paste it on here. Hope this helps you.
