Basic questions about flash

I got this rather weird question about flash. I don’t get the program itself. Like I know what a frame is, but what the hell is that when I double click on it.

And also, what about the layers? is it the same as in Photoshop? Do I need to make a new layer for every graphic?

And what about importing images? they seem to get really choppy and they’re low quality? Find it really hard to understand the basics of flash. Photoshop wasn’t that hard :puzzled:
