If you only want to see if it already exists, just calculate an MD5 hash of 
the file's URL and see if the result exists (see 
kdebase/libkonq/konq_previewjob.cpp for the algorithm used - or 
kdelibs/kio/kio/previewjob.cpp in KDE 3). If you also want to create a 
thumbnail if it's not there yet, get KDE 3 and use KIO::filePreview() :-)

Please note that the cache location will change once Qt 3.1 will be available, 
it will then conform to http://triq.net/~pearl/thumb-spec.php
