I'm new to FC and i don't know if i can make a picture gallery in FC and then send it to my Flash page, by importing it...
If i can, how can i do it please?
It's very important for me because i don't know too much of AS3 and an animated gallery is much better than a static one...
Unfortunately you are unable to take your Flash Catalyst projects and use them inside Flash Professional. Catalyst is built atop the Flex 4 framework, and thus not compatible with Flash Professional.
There might be some solutions, but I imagine that they would require a fair amount of AS3 to execute.
