Having the appropriate understanding of editing CSS for the background image modification, now let's have a look again at our global.css file.

You will notice there are quite a number of background images used. While going through the global.css file, you will notice that a number of these background images are used in the various parts of the default theme you are modifying and working on.

For the purpose of this exercise we will look into all the important background images you will need to upload to your theme1 folder. Remember, you want to create a new theme and it has to look unique.

Go to the theme1 site (your copied default theme file) and browse the site through Firefox. View the information for the image you want to change. Next, list the background images. You can also refer to the image folder in the default theme files that you have and review each image.

Make a list of out the images you want to overwrite.
