How to: Art

I have a question! I don't know much about creating apps or games so I guess im concidered a noob. Anyways, when I draw something on regular paper, I take a picture of it on my ipod touch and I just send it to my email, then on my computer I open and save the picture onto my files so I can use that for my app. But lets say I draw like a ball and take a picture of it. When I use that picture it comes out with the white blank part in the back (which is the paper) but what can I do to the picture so only the ball comes out and not the blank paper in the back?
And sorry if you don't understand what i'm saying, its kind of hard to explain. But you know how in the gamesalad shop, you can buy like just pictures of trees or just anything else? Well i'm basically wondering how I can make my drawings like that... except... they're hand drawn. Thanks ^_^

    If I am understanding you correctly, you are trying to get a transparent background? If you don't have something like Photo Shop, I recommend Gimp as it is a free down load and can help you with what you need. What are you using to draw, just paper or are you using a program?

    Yeah actually I might drop in here too, I use Adobe Illustrator CS6 and anything I scan in comes out with a white square background (the minimum size that would cover the character). I have trawled heaps and heaps of Adobe forums/tutorials but all of them seem to lead to something more complex than what I'm after (like removing a person from a photo or something). All I need to do is get rid of the white.

    @BazookaTime can you assist me also?

    First download gimp, its free and they have it for mac and windows.

    Second import the photo of your character into gimp, go to file-import and select the picture.

    Next crop the image around what you want, ex: the ball.

    Then hit file-new then make sure it is transparent.

    Go to your first image and hit select-all then copy it and then go to the new transparent image and paste it.

    Then in the next image erase all the white borders.

    Ok if you have illustrator you need to use live trace then expand which will give you a nice vectored outline of what you were drawing.

    If not then consider downloading gimp and retracing it using the shape tools on a new layer.

    Gimp: the magicWand is instant Alpha … apply and cut
    or use select by color … if no white in ball… and cut

    easy to see in your
    … Select Area icon … click the ▼
    click the Instant Alpha … use on white area …
    when all the white turns orangish … [option]+[X] … or Edit … Cut

    OHHH ok cool thanks alot! And another question, most Hand-Drawings should be scanned right, or like what I do does that work too (Taking a picture of it on a phone/ipod, sending it to email)?

    @HakunaMatata … taking a pix or scan is just fine …
    both require delete of the background by removing its Alpha channel
    … often use a pix for guide/starting point in my imageEditor

    also, think putting a drawing program on your iPhone/iPod/iPad
    might also be fun to do! … and give you nice images!
    lots of nice free apps … search "draw free" … in iTunes … see all
    IMO … drawing on the mobileDevices seems so much easier than drawing on desktop!

    The difference between scanners and cameras is that cameras use a lense.
    This gives some distortion on the edges of the photo. Specially when you use your phone which uses cheapish lenses. Draw some straight lines. Take a picture and you will see that the lines are bended on the edges.
    When you take a picture of your drawing have it in the middle of the picture and not too big so it ls less distorted.
