Found it through the source when changing your avatar. I haven’t been able to find sites that let you get a picture of your current Spartan armor and colors with your in-game pose. The poses are generally left out. You can save a pic of your current Spartan WITH it’s in-game pose by going here:
https://spartans.svc.halowaypoint.com/players/Co2%20Outbr3ak/h4/spartans/posed?target=medium
Hints: Change my Co2 Outbr3ak gamertag out with yours. If you have a space in your gamertag, then you must put in a “%20” without the quotes where the space is. Also, you can change the size of the picture by changing “medium” in the url to either small or large, and pressing enter to reload the page. This way you can get a bigger, better-looking pose shot than the forums will let you.
