how in the world do i disable KDE 3.1-10 for Redhat 9 from making thumbnails of images? it's taking up valuable space on my drive. i've gone through all the configure settings of KDE and konqueror, and i can't find anything related to it. i've disabled previews, reflect file/image contents and the likes, but still it's doing thumbnails!

google search says, in one document, that these thumbnails are needed by KDE programs, and will always be generated. having these thumbnails cached, in fact, will make the apps run fast as they don't have to regenerate the said files.

or i'm guessing this can't be turned off and so i'll have to have daily/weekly clean up jobs to keep the caching down???
