I hate it when they change this program and you have no idea where to find something!!!! Where did the button to change the background go. It's late on Saturday night and I have a lot of work to do.
If you would like to change the background of a service item, there is a link above the generated thumbnail in edit view that is labeled 'media library'. Next to this is the word 'file'. If you click this, it will open up the media browser (the new way to search through backgrounds) and you will be able to change the background. You can also do this by opening the media browser by clicking the 'media' link in the top left portion of the main window, then choosing the background you would like to apply. Does this make sense?
It has been put back in with the latest update.
You're not alone. I didn't know where the background button went either.
