You have a couple of options. Both require that your images are all on separate layers and that they are properly lined up. It's the same requirement you have if you make a flipbook or are doing traditional cell animation.
It is a good idea to sequentially number the images. Something like pan_001.png, pan_002.jpg, and so on.
When you have the images all prepared all you have to do is import them as an image sequence. This will make a movie out of the images. You can change the frame rate by interpreting the footage. That would be the most common way of creating a movie from sequential images.
To control the timing of the images you enable time remapping.
The other option is to import all of the images into the Project Panel. Then you can select them all, in order and choose "Create Composition from selected" from the file menu. You will be given the option to create multiple compositions, or a single composition, or a single composition and sequence the layers.
The third, and least efficient workflow is to import all images separately, add them all to a timeline with one on top of the other, then set an in and out point for all layers and use the Keyframe Assistant to sequence the layers.
The basics of this workflow are in the online documentation and you should spend some time with the User Guide and in the Learn workspace so you get a handle on the UI and basic workflows.
