I need a few bug fixes and alterations to my site

My current site DavidMacG.com has a few bugs that need fixing and I need to add some functions. the Random pic loader - loads blanks sometimes! the over all loading is slow. and I need a way to add text and buttons for text - that can be changed/updated by me the useer. And it would all be great if I didn’t need to be a Flash expert to do all this. The designer failed to inform me that I’d need Flash and the knowledge to use it to update ANY INFORMATION of my site.
So I’ve figured out how to add pics but to change/add a few functions has befuddled me.
All programed in Action script and the .fla is available for all who ask.
If you can help - thanks
