Go to File>new>blank file. In the w & h fields, enter the dimensions of your paper stock. For printing, it is best to have the resolution in the 240-300px/in range.
It is desirable to have the resolution of the blank file the same value as that of your picture files.
Open your picture files, and drag each one from the photo bin into the work area.
Each picture will be on its own layer
Access the move tool to position the pictures and to resize with the corner handles of the bounding box.
Go to the View menu, tick grid & rulers. This will help with orientation
If the picture are an odd size, do the math and crop (with crop tool). Do the cropping before you drag them from the photo bin
Your 4 pictures will be on separate layers. Make these 4 layers active (click on each layer while holding the CTRL key on keyboard). Now, on the move tool's option bar, at top, click on align to vertical or horizontal centers or the edges.
That's so useful, thank you so much. I'm taking part in an end-of-year class exhibition and have been struggling a bit with Elements and you're help has really solved a lot of headaches. But I may be back for more!
