Hi
There are 2 ways of opening it up with another program.
First way is right click with your mouse on the image file and select open with. If the software is not there select choose program and then select the software you want to use from the list.
Second way is right click on image file and select properties. Under general you will see 'opens with' and a button next to it which says 'change'. Click change and again select your software that you wish to use from the list. This way will change your settings for all images of that type to open with the selected software in the future. Don't forget to press OK when you come out to set what you have changed.
