To address the OP's question, generally speaking you should use the 'reply to thread' button to post pics, format your text, etc. As opposed to the quick reply box at the bottom.
Bear, that's strange. Because it's not happening to anybody else (or at least it hasn't been brought to our attention), it's probably an isolated issue. I remember we had to work through some other things a while back that were effecting you specifically. Sounds like software or browsers need to be updated on your end. This forum is HEAVILY customized, including lots of things you probably won't see elsewhere because I do alot of the coding myself, however most modifications do not contain or effect any functionality that I could imagine would cause the issues you're describing.
As far as the 'thanks' button and your page reloading, that's definitely not a forum side issue, and that's bizarre. The thanks button is actually 'ajax' based, meaning the action happens in real-time in the background and doesn't require the page to refresh/reload to display the new data.
Just out of curiosity, is your .NET framework, java, browsers etc all for the most part all up to date?
