There are 2 ways to submit a photo of a Rogue.  You can either upload a photo from your computer, or if there is already a picture of this rogue on the internet somewhere, a dating site for example, you can tell RogueDaters.com where the image is, and we'll load the picture from there.

Uploading a picture
Uploading a picture is exactly like uploading images to any site such as Facebook or MySpace.  On the Add a Rogue page, click on 'Browse' and find the file on your computer.   Once you've done that, click on 'Add Photo'.  Your photo will then be uploaded and resized automatically to fit the website.

Point to a picture elsewhere on the internet, such as a dating site
In a new window, go to the website and find the image.  Depending on your browser, you should be able to right click on the image and click Properties.  On the properties window should be a URL of the image.  Copy and paste this URL into the URL box on the Add a rogue page and click 'Add Photo'.  The photo will be automatically imported from the other website and resized automatically to fit the website.
