I know that. I believe the image was only linked (not embedded through the [img] tag), so it wasn't using the forum proxy. The script looks for all links (embedded or not), so it was trying to upload it anyway.
I still think it's worth uploading it, since imgur could delete our images at any time.
Right... I hadn't thought about that perspective.
What size could be reasonable to allow uploading? Do you think 5MB would be acceptable?
@LoyceV based on your collection, what value do you think is reasonable?
