The following tutorial covers adding content image to SkyCream theme on a Plone 3.3 or Plone 4.0 website. Diazo SkyCream theme allows displaying image carousel in that place - see How to insert image carousel to SkyCream diazo theme in Plone 4.1 tutorial.
1. Front Page Content Image
SkyCream theme can include an image above site content area. This image is used can be displayed on all site sections unless they have different one set. Default image size is 589 px width and 351 px height.
In SkyCream theme version for Plone 3 - this image with photo.jpg shortname is located in a site root. In Plone 4 you can add such image to site root, and give it photo.jpg, photo.gif, or photo.png shortname.
To change this image simply go to its edit form and upload different image instead.
After you replace this image with a new one - your content area will now look this way:
Default content image size is 589*351 px, this is the area reserved for content image. But content image width depends on the second column width. The wider column is - the narrower content image will be. Content image height depends on photoBgHeight in base_properties. See more detailed information on customizing columns width in base_properties in How to change SkyCream columns width section.
