Photoshop Help

[SoldierX77]

I just got Photoshop recently... And I just made a spray... So I saved it as a .jpg but it comes up all weird, like the bottom half is all static and the top half is split into three sections of the correct format but a little bit staticy... I talked with someone and they said to save it as a .tga, but none of the formates have a tga in them.. Anyone know how to fix that, or what to do?
Thanks.
