Thanks for the input, but it doesn't, unfortunately, help - I have those 
files too. I presume you are using PIL 1.1.4?

I thought it might be a 1.1.5b1-specific thing, but sadly a de-install 
followed by a re-install of 1.1.4 gives me the same error - a dialog box 
appears telling me that libjpeg.dll can't be found in any of an umber of 
directories (not surprising, since there is no such file on my disk).

I thought I'd fixed the problem by copying jpeg62.dll from GTK 2.0 and 
renaming it as libjpeg.dll, but unfortunately Windows then started 
complaining about the absence of libz.dll (and a copy of libz.pyd 
definitely won;t do the trick).

So I'll copy this to the PIL support list and see what the gurus have to 
say. I'm wondering if there could possibly be any interaction between 
the Cygwin and Windows versions, since both are now loaded on the same 
machine. Bit stumped here ... I don't remember PIL being so 
temperamental before, and it's working beautifully under Cygwin.
