Use either the following HTML or Textile markup to add an inline JPG/PNG image to a custom page:
HTML markup:
<img src="IMAGE_URL" alt="IMAGE_DESCRIPTION" />
Textile markup:
!IMAGE_URL(IMAGE_DESCRIPTION)!
Where:
IMAGE_URL is a URL pointing to the image (eg http://domain.com/path/to/image.jpg).
IMAGE_DESCRIPTION is text describing the image (eg "A flower in bloom").
