how do i merge 2 png images without losing transparency?

[XxHackThisxX]

Hi all.I am trying to merge 2 png images,both different sizes and with transparent backgrounds.After i merge them i will need to resize them to fit into each other correctly.But i cant seem to do this without losing transparency.It seems that the only way is to create a background image and then set them onto that image,and merge them together that way.Is this the only way i can do it? I dont think i will be able to create a transparent background again after they are merged together because of the difficulty of the image.

what program are you trying to use bud? photoshop it shouldn't be to difficult to just overlay one or the other in layers then save them
