You probably need to change your settings. At the top of the QB page in the brown menu bar click "settings"
At the next screen on the left, scroll down until you see the box titled "My Settings" then in that box you will see "my account" and under that you will see "general settings" click "general settings"
Scroll all the way to the bottom to find the area called "Miscellaneous Options". The first thing under that is the message editor interface. Click the button next to :"Enhanced Interface - full WYSIWYG editing"
then scroll all the way down and click the box that says SAVE CHANGES.
The next step will be to make sure your pictures are resized so they aren't so many pixels. there are instructions on the board for doing that but I found it much easier to just change my camera settings. good luck!
