[Community] Get Image using owslib

[Dominic Lowe]

Hi Manel,

Okay thanks - it is still a problem though as it should use the method from 
the utils module (which allows with or without a "?")

I just looked at the WMS code though and it's not as straightforward as 
replacing the opening method - I'd forgotten the wms module has some extra 
code to handle HTTP password authorization when opening urls. So this should 
probably also be moved into the openURL method in the utils package (which 
also solves the "?" problem).

Thanks for bringing it to our attention - I'll make a ticket for this issue. 

Cheers
Dom
