I am using Flash for the first time so I don't know a lot yet, but I want to
create a Flash Movie of the sun going down. I have taken digital photos of the
event, one every 5 seconds (about 110 frames) and now want to create a Flash
movie to show it on my web site when it first opens. How can I do this please?

well you said the magic word "110 frames" frame animation is the most basic
concept in flash make 110 keyframes and place your images in each or you can
import the images as a sequence. Be prepared for a very large and slow loading
flash file, even compressed... lets see 110x 30k = 3300k or 33m that' not going
to load very fast even on broad band , you should consider using a video stream
to do this
