I learned a lot about flash from lynda but it does cost 25 bucks a month but I can honestly say my subscription to Lynda has been well worth the money.

I'll tell you a secret as long as it stays between me you and the rest of the web I use flash extensions for most of the stuff I do in flash because it makes the job easier and there is enough HTML, CSS, PHP code floating around in my head. Remember Keep It Simple

For slide shows I use an extension called Slideshow Pro, cost $39 the time it saves me Priceless
