Hi,
I will be able to say anything after looking the source code.
As the picture is not yet live, so it is hard to say anything.
Just a guess,
Picture dimension should not be changed as the width is very small i.e. 200px. Only possibility can be, that picture is wrapped in a parent div which has width less than 200px.
Please make it live to some post with the same problem, so i will be able to guide you.
Thanks
