To add background images, go to the theme options panel (Appearance → Theme Options) then Background → Images. Click the Upload button and choose your images, you can select multiple images to upload more than one at the same time. We recommend that your background images are 1920×1080 pixels (w x h) and you should try to keep the file size as low as possible without sacrificing image quality, we have found that a file size of 300-500kb works fine for each image. You can make the image any size though and the background script will scale it to fit the browser window.
You can set any background image to have a caption which will be shown when the website is in full screen mode. To set add a caption to an image, hover the uploaded image thumbnail and click the cog icon.
The background images can be sorted into a different order by dragging and dropping the thumbnail image into the required position. You can then proceed to configure the background image script, if required, with the other options on this page.
