open flash > 3 layers x 35 frames, might need more layers later for buttons, text ect, place the posters 1 on each of the last 30 flames, this many bitmaps are going to need a preloader, get one from the net,
convert each poster into a 'movie clip' >modify > convert to symbol > movie clip,
go into each 'movie clip' and convert the poster into a 'movie clip' again, this where you do your magic with the magnafier (never done that myself) but there's a load of free action script sites out there,
go back to sceen one (button above start of timeline) make another layer, call it buttons, numbers 1 to 30 if you want to do it like that, convert each button into a 'button' >modify > convert to symbol > button, on button one add the action script ,,,,,,,,,on (release) {gotoAndStop(6); },,,,,,,, button 2 same again up the number in the script to 7, rinse repeat,,,,,,,,,,,if you dont want 30 buttons just put a 'next' button on each poster/page/frame, on (release) {gotoAndStop(Next); },,,,,,,,
there's many ways of doing this job but i think thats the easiest, well easier still, send it all to me
i'll be busy for a few days but i can make a start for you, once you have done one poster it's just a case of copy & pasting the code, same with the buttons,
