HELP! Layering photos???

So I'm trying to layer a photo (I think) but I'm having trouble. I use Microsoft Digital Image but can't figure this out. Basically how do I get the sequenced shots on one background?

I know there are other posts with the same questions but I didn't see any that used the same program.

Thanks

I've never used MS Digital Image, but my guess is that it works the same as other programs. I simply create a blank 'new' image with given dimensions (I make it really big so I can slam as many pics on as I need to). Then use whatever key combo is required to 'move' the picture you want onto the blank 'new' image. I do this with all the pics for the sequence and each new pic added comes up as a new 'layer'. Sorry if this isn't a help.

I still can't figure this out.
