  • An individual may submit one image to be posted on the web site.
  • The image must be in a JPEG format and should have a file extension of ".jpg".
  • Image files larger than 700 pixels on a side or larger than 180k in size will be resized to fit the gallery. 

Most image programs have utilities that allow you to reduce your image file size and dimensions.

Alternatively, some web sites, like NetMechanic, offer a free service that will allow you to reduce the size of your image without any loss of quality.

Or you can fully optimize your image with Pixlr's free on-line editor.
