I would like to print and 8x10 as a full page of wallet size photos

Wallet sized photos are 2" x 3" or 2.5" x 3.5" for the most part which will give you 8 photos per page. So do the following:

1 - Once the photo is in iPhoto put it in an album and crop it to the wallet size ratio you want: 2:3 or 2.5:3.5

2 - Duplicate the photo 7 times so you have 8 copies to fill a letter sized page.

3 - Select all the photos in the album and start the print process.

4 - Select the paper size in the upper right hand cornder and select the print size in the lower right hand corner.

5 - Print

You really believe those profiles? 😉 I made an assumption that the user was running 9.5. If it's 9.4.3 then it would look like this. Still essentially the same.

With iPhoto 8 (09) one wouldn't have to duplicate the file:

good instructions for iPhoto '11 version 9.5.x🙂 but since OP states that they have

iMac, Mac OS X (10.6)

They clearly do not have iPhoto '11 version 9.5.x - hence my indication that we need to know the version in order to help - as you know the steps are different in different versions and they could have pretty much any version except 9.5.x 😍

Scan it as an RGB image, import to iPhoto and follow the instructions for your undisclosed version of iPhoto to print multiple photos of your desired size on one page
