how do you print multiple pictures on one page using microsoft photo editor?

Open Microsoft Photo Editor, click on File > New

Set to True Color, make the size same as your paper size and set the resolution to 200 Dpi then click OK.

That should open up a white space for you to drop your photos into.

Open each photo in turn and copy/close/paste it into the white space.

You can move each photo around to position it before pasting the next one in but unfortunately you can't re-size them.

When you have completed dropping your photos in, click on File > Save As to save the image if you wish or just go straight to File > Print to print without saving.

If there isn't a good microsoft photo editor, Then learning adobe photoshop is really easy. Just watch turorials in youtube or begin learning online through various websites e.g. Adobe tutorials etc..

I am not familiar with this program. You might check out stitching the pictures together. The programs I use have "Stitch" listed under Edit.
