Part 2. How to Change GreenJet Theme Top Images
The following tutorial covers changing of GreenJet Theme top background image on a Plone 3 website. Instruction for changing it in Plone 4 - see in How to replace GreenJet Theme top image in Plone 4 tutorial.
1. Front Page Image
GreenJet theme includes an image, that is used as a background on site top area. This image is used on all site sections unless they have different one set.
This image with top.jpg shortname is located in quintagroup_theme_greenjet_custom_images folder (in ZMI). To change this image press on Customize button:
Then press Browse button to select the your own background image. After that click on Upload:
Now you see your new background image, and it is automatically put into custom folder:
Now when you return to Plone interface, you'll see new background image.
For the subsequent logo replacements go directly to ZMI portal_skins/custom/top.jpg and upload new background image there.
Default background image size is 999*159 px, this is the area reserved for top background image. In case your new image is larger - it will be copped. In case it is smaller - black background will be displayed, like this:
2. Site Subsection's Image
Every site section can have unique background image with GreenJet Theme installed. To change default top image for a certain folder, add an image with section.jpg shortname into it, and this image will be displayed instead of the default one.

Upload the image you want to be displayed as a background, and give it section.jpg shortname. Make sure your added image id is section.jpg. If not - use Actions -> Rename menu.
Now this folder and all its pages will have this background:
GreenJet theme comes with 3 predefined background images for the front page and 2 example folders:
