Google Docs – How to Create a Background Image

A few ways to do this, none of which are perfect:

• Apply background to all. Go to the Format menu, select "Change Background", select your background, then choose Apply background to all slides. Unfortunately there isn't an equivalent for text colours.
• Choose from an existing theme from within an existing presentation - these are a bit limited, but at least do apply background, font, colour etc across all slides.
• Choose from an existing theme when creating a new presentation - there are a load of templates set up when you go to "Create New" -> "From Template" - maybe you can find one there that suits?
• Make your own theme - you could make your own theme if you follow this: Template submissions: Submitting a template This works only if you have a paid Google Apps account. I believe that you can also create templates with public @gmail.com accounts, but these will be open to the public

There doesn’t seem to be an upgrade tool available within Google Docs yet. The only way I can think of doing it is to create a new empty document and copy and paste from the old document to the new document.
