Need help on mouse over

I have been looking everywhere I cannot find anything on it just because I think either I am searching the wrong words or its so obscure I cannot find it.
But Anyways I need help. I took a ton of pictures to make a 360 degree rotation of an object What I need to do In flash is make it so I can roll over the left or right side and it will switch to the previous or next image to make it look like it is rotating.
I have searched on mouse over go to, etc.
If you guys could either give me a hand or point me in the right direction That would be amazing, Thank you in advance.
