For the average user Microsoft Paint is just a basic image editor with limited functionality. It never occured to me that artists could great pro images even with such a basic image editor. I probably would never get in contact with works of those artists if video sites such as Youtube would not exist. Thankfully they do exist and I was able to select some handpicked images that have been created with the Microsoft Paint image editor.
GIMP Image Manipulation Program
If you ever had the problem that you needed a good graphics suite and always thought the Adobe Photoshop line of products was far to expensive then GIMP might be the right software for your. The biggest advantage, its completely free, you don´t pay a dime for it.
