How to tell if a site is powered by Coppermine ?

[viluve]

Hi hi,

I went to a local photography site called www.fotografer.net ,
the structure of the site is very similiar to what's available in Coppermine.

However I didn't see any 'Powered by Coppermine' logo in any of the pages.
I tried to use view source, hoping maybe it'll give a clue on what cms they use.

Is there any other way to identify, if it's powered by coppermine ?

looking at the html output I'd say it's not based on coppermine, as there are no css class names nor other coppermine-typical things on that page.
