The very basic image-editing program I knew when I found out that I love sketching and designing was MS-Paint! Of course, it would help a lot if you learn a higher program aside from the very basic brush and drag feature of MS-Paint to fully expand your skills in image-editing.

Certain softwares were created to suffice the needs of the on-growing skills of a designer. Photoshop and Corel Draw arrive in the scene. Since some of us could not afford purchasing software like these, unless you maximize the use of torrent sites, software publishers created an online extension of image-editing software.
