Drawings to JPEGs

For my drawings to be used and animated in Flash, I had to scan them into the computer and alter them so that they were clearer and cleaner line drawings. I initially was thinking of using llustrator to do this, using the trace image tool, however most of my scans of my drawings would not open in Illustrator.
I tried to resolve this problem, but instead to I decided to use Photoshop to create the simple line drawings instead.

I opened each image in Photoshop and deleted various parts of the image so that I was only left with the line drawings. I added a white background, which helped me to find any odd lines or marks to erase, and then enhanced the black lines to make the drawing stand out and become clearer.

I then saved each of these images as JPEG image files ready to use in Flash.

Here is an example of one of my scans after my drawings after it had been altered in Photoshop:
