Editing theme images using Finder
Background images used by most RapidWeaver themes are stored inside the theme contents. This ensures that the images become an embedded part of the theme and can be selected for use under the theme settings. For example, you may want to have a different image displayed on different pages of your website to add some variety.
The theme contents can be accessed by CTRL + Clicking (or right clicking) on the theme preview icon in RapidWeaver (the small picture of the theme which appears in the theme pane). From the popup menu, select the Reveal theme contents in Finder option. A new Finder window opens which contains a selection of files and folders. Open the folder marked images. Then inside, open the folder marked editable_images. This editable_images folder contains all of the images used by the theme, including blank placeholder images. Placeholder images are typically white or grey in colour, and named or numbered sequentially like bg01.jpg, bg02.jpg, bg03.jpg, header-01.jpg, header-02.jpg, header-03.jpg as an example.
Any of these placeholder images can be exchanged for your own images. Swapping images like-for-like means that your images become available for section in the theme style settings. When you add new custom images, name them so that they overwrite placeholder images. By replacing the placeholder images supplied in the theme, your custom images will be available for selection under the theme settings. When creating new images, it is advisable that these are optimised for the internet - typically this means they should not have any specific colour profiling applied and be of 72 DPI with a file size no greater that 100KB.
