What is the association between Adobe and Macromedia?
Just downloaded Flash 8 to try. Also watched the tutorials, but gave up half way through as they seemed to move off track from beginer to intermediat user. What is the best way to learn the basics of Flash 8, apologies if this is very basic for you guys, but I am a photographer and I am sure I could show you a thing or two about photography…….mark
Hi Mark,I’m not too sure which tutorials you’re using, but this tutorial (in 3 part series) covers the basics and fundamentals of using flash 8.http://www.adobe.com/devnet/flash/articles/intro_flash.htmlhttp://www.adobe.com/devnet/flash/articles/intro_flash_pt2.htmlhttp://www.adobe.com/devnet/flash/articles/intro_flash_pt3.htmlHope this helps,Jen.
