doubt about an image

[fdle]

Which could be the purpose of the image below, which was found on a page belonging to the hypothetical site www.domain.com.

< img src="http://www.seconddomain.com/image.gif?track=6bb3f01axu7Y&aid=00995"
width=1 height=1 border=0>

asked:

Which could be the purpose of the image... "/image.gif?track=6bb3f01axu7Y&aid=00995"...?

Um... tracking, maybe, with the query string providing identifying information about the page and/or tracking account...?

(Lacking information about the natures of the two sites, it's difficult to say more.)
