Unfortnuately, there is not really a two line answer to your question.
There are a few ways of doing this that I can think of off hand...
1) Use some video editing software. Any NLE that allows you top use stills as assets will do. You need to create your timeline for your 'movie' then just add your stills to the timeline. Once on there they can animated if required and transitions between pictures can be introduced. As an editor I prefer this solution because it has the most flexibility and control and you then have the software to edit 'real' video as well.
2) Some DVD authoring packages contain functionality to allow you to quickly create a still slideshow with a minimum of fuss.
3) Finaly, I'm sure there are a number of bespoke software packages out there just for this purpose. this is likely your best option if you do not want to dip you toes into 'real video' editting.
