Blogger: my call for help...

Just a quick question for my fellow bloggers out there regarding image placement- it's irritating me no end! For those who use IE to view my blog, you would probably have recognized my problem already: the strange gaps and formatting appearing in my posts between images every now and then because I myself use Firefox.

Take my latest post for example:
I guess my question is: What can I do to, in a sense, standardize the look of my posts between different browsers?
(I'm not even sure whether my call for help makes sense or whether it's just a jumble of words... but if you have just an inkling of what I'm on about, and know a possible solution, I would greatly appreciate any form of contribution!!)
