I love Paint.net! 

It is a must have program for any Windows user.  It is far from your default paint program that came with your PC.  It features a very innovative user interface that supports all type of features and tools.

Another benefit of this free software is it has a huge community of developers.  Here are some of the tutorials they have put out for the rest of use to learn from.

They cover newbie tutorials, image and photo touch-ups, text effects and tons more.  If your looking how to get something done with your images; there is a good chance they have covered it in one of their many tutorials there.

Check it out, and let me know if you have any favorite tutorials that helped you out.   

Really that's a very good reference by you. I am just new in graphic design, I am sure it will help me out. I also want to make the animation but I was just searching something of getting started. Its a good job done by you. Keep it up.
