Another step in creating your animation, you are to find an image to put yourself into.
Here is a step by step tutorial: Copy Paste with Adobe Photoshop
Make sure you select and image that is a decent quality first check the pixel dimention of your image click "Image">"Image Size" and then note the pixel dimention and when you scroll over an image in Google, the pixel size should appear. Don't select anything that is significantly smaller than your portrait.
Once you copy and paste your background into your portait comic image, then follow the same steps to stamp and colour your image. Drag the background image beneath your portrait on the layer palet. Erase part of your portrait layer to expose the background. Save As "YourName with Background". Make sure your portrait is in the share folder.
Good Luck! Have fun, be creative and problem solve as much as you can...
