Failed to download valid cover

[Pr.BarnArt]

I like to download a cover p.e. with this url http://www.inmondadori.it/img/Le-luc.../BL/BL/01/NZO/

But this gives an error:

Starting cover download for: Le Luci Di Atlantide 
Query: Le Luci Di Atlantide [u'Marion Zimmer Bradley'] {u'isbn': u'8878195820'}

AttributeError: 'module' object has no attribute 'KEY_COVERSIZE

I cannot fix the problem, no idea what is the cause ( or it must be the url itself: it is an html page where in the body there is an img class. The src of the img is the same url again).

That's an error in the plugin's __init__ function, you need to fix that.

Thanks, I must have been sleeping . I changed the code myself a long time ago and did not check that part.

So I indeed needed your wakeup-call.
