Hope you get through it without any damages. News sounds horrible.

I think as long as the authors of the Horde_Image code agree, there's nothing 
stopping you from licensing it as GPL. On the other hand, if the library is 
LGPL and uses GPL code, this should also be no problem by itself. Users just 
need to know that GPL parts are included.
