HS - I understand that - and what I'm saying is that this has been an issue for many people - that it's automatically inserting thumbnails and not giving the option to change that to original size...
"But when uploading in IE, there was no option for the original."
"for some people, the option on the menu to select thumbnail or original isn't available"
I wish I had a screenshot to show you - it puts a thumbnail in the post, and there's a strikethrough on the first line of the menu where you'd normally switch it to "using original".
I've seen this question coming up a lot lately - and experienced it myself.
