Squashed images advice requested

Hey guys and gals,

So im working on this 2d game, right? And i finally get something to display correctly on the screen! (Commence gasps and shocked fainting) the problem is, all the images are squashed around, distorted, and badly abused. My hero actually looks  like hes crying! My game is at a 800x480 resolution, and so far my images are drawn on ms paint at 130x130. Can anyone point me to another thread or give me some advice on how to make my images unsquashed?

 

Please. Help the crying knight. XD
