Image source Type in the the filename or URL of the image to include, or press the Choose file... button to select one from your harddrive.
Image is relative to page location If checked, then when press OK, it will calculate the relative path from the currently opened document to the image. Relative paths use commands of .. to say "go up a directory from the directory this page is in". This feature is not yet implemented
Alternative text Type in some text that will be displayed for an image that is viewed by a Plucker user who has their images turned off. Strongly recommended.
Color If you are including a black and white image, and you would like the black replaced with a different color on people who are viewing it in grayscale or color, you can select a color with the Choose color.. button. Using the same compiled output file, a black and white user sees the black and white graphic and color users see the color graphic. This is also a way to give color graphics with an absolute minimum size of the output file.
Hyperlink Images can be used as hyperlinks. Type in the URL or file that should be jumped to, when the user taps on the image.
