Merge 2 Pics so you cant see boarders

Hi all,
I have 2 pics that are basically the same colour. I would like to merge them into one, on top of each other so you cant see that they are 2 separate pics.

Cant seem to work out how to do it though!

Think i have explained it ok!!

Thanks in Advance

can you post the two pictures and a little detail on how you wanted it arranged? Many different merge techniques depending on what you want it to look like. Makes it easier to give you the information you want.

put the two images in the same file as two separate layers.
select the top layer.
then from the layer panel, select the dropdown box with "normal" in. changing this will have various effects one of which will do what you want i'm sure.
when highlighted, i.e, blue, you can then just use your up and down keys to scroll through them.

Hope that makes sense.
