OverviewYou need two images to work with -- a JPEG image and a GIF. The effects here work best if the JPEG is a detailed painting or photograph, and the GIF is a cartoon or line drawing.
You can use images you created, or find new images on the Web. Save both images in a floppy disk or anywhere else you can find them. Make a note of the names of both images, their file sizes, and the URLs you got them from (if they are not your own property).
In my examples below, I will use the filenames ship.jpg and bird.gif for the original images. Your images may have any name you like. In this homework, you will make seven images by modifying those two images, and make a web page with all seven images on it.
This technique uses a free online graphics editing program which is funded by advertising. Some of that advertising is annoying, so expect to see some pop-up ads as you proceed. If you see any Security Warning windows asking you to install toolbars, click No.

NOTE: Some GIFs on the Internet are already transparent. If you want to remove transparency information from an image, in the drop-down list titled Edit at the top of the window, select Convert to change it to a JPEG. Then select Edit, Convert again to change it back to a GIF. Now the image has lost its transparency.
