convert picture to line art like a picture on comic cartoon

[cafenet]

how and what the software to use convert from image picture to line art?????

[freecrm]

Photoshop (I'm on CS3)

Under filters, use either stamp or trace contours, depending on the effect you want.

I would use Adobe Illustrator (depending on what the original looks like) live trace the image and then you can add a stoke and play with different widths and fills.
Live trace has many options - you may want to use 4-16 colors or just go black and white.
