I use photobucket, sometimes it can be forum related I believe as I have noticed the same picture posted on the owners club forum which has a different software base looks bigger than it does posted here ( maybe it's in the settings somewhere either forum or even device related but I don't look after that side of the forum so have no solution )
You could try just posting an album link from photobucket , maybe others will be along with alternative hosting suggestions
I have just downloaded TinyPic to give it a try but it seems you have to click on the code to see the picture but this is my first attempt so might be other options
