Cannot connect to/Cannot open/Could not fetch errors in PHP log

[billjust]

First- if this is not the right forum or community for this question, please accept my apologies.

 

I've been getting odd entries in our PHP error logs that look something like this:

[05-Feb-2008 07:51:26] Cannot connect to www.ourwebsite.comhttp:80 - (52687668)

[05-Feb-2008 07:51:26] Cannot open http://www.ourwebsite.comhttp://holegirl.eclub.lv/.images/pictureofme?

[05-Feb-2008 07:51:26] Could not fetch: http://www.ourwebsite.comhttp://holegirl.eclub.lv/.images/pictureofme?

 

Obviously 'ourwebsite' is different, but the rest is the same.  I'm not sure if this is someone hacking our site or just try to relay through it or something, but I don't think it's working for them.  Does anyone know how to interpret this and what I could do to stop this traffic?

Thanks in advance!
