Lycos' HEAD vs. GET

Hi,

I looked at our access logs here and noticed that Lycos' Web Robot(s??) uses
GET to request all non-image files/documents (.html. .txt, .ps....) and uses
HEAD to request various image files (.gif, .jpeg...)

what I don't understand - why doing even HEAD on the image files ? What is
the benefit of verifying the existance of images on the Web ? I can't think
of any .....

Does anyone know the reasoning behind Lycos' HEAD requests for images ?

Thanks,

Otis
