Forum Inserted images are small... not full size even if I select that option
 

When using the insert image feature, I can highlight the image (that appears initially WAY too small) and edit how it appears, selecting "center" and "full size"... yet full size is never full size. If I hover on the image it will say "click for a larger version" but clicks do nothing.

is this a bug? I've seen similar reports and questions but nothing seems to apply.
