I use the 'add image to post' function and I think all of the pictures end up to be the same size as there is max size limit.
Your Dratz image above is 452 x 640 (nice and large) but this one is 126 X 180 and small.
I've been stumped by this inconsistency in the size of posted images.
(If you want to send it to me in a PM, it should come thru large, as I've never had an issue like this on PM, and I can post it via Photobucket)
It would be nice to know what the deal is...
