Posting Photos on Blogs

I've had this problem for a while now. Whenever I want to insert a photo into my blog it looks like it is centrally aligned while I'm editing -the centre align button is activated- but then it jolts to the left when I go to preview or publish:

Editing=

Published=

Has anyone else had this problem? Any help would be greatly appreciated.

Yet both are centrally aligned in a forum post?

I have this problem all the time.  There seems to be no rhyme or reason why images sometime will be center aligned bit other times won't.  Usually a hard break or a paragraph break ( <p> in html ) will allow for a change in alignment, and indeed, sometimes it works, but sometimes it doesn't. 

It's rather annoying to spend 2 hours trying (and usually failing) to work around a problem that should even exist.  

I think I've found a method which works. Before inserting the image you want, click the centre align button first. It seems to work for me now.

I'll give it a try - -though I've tried so many work-arounds, I can't remember what I have tried.

Thanks.
