when you are ready to cache the image, you can now call: insertIntoCache(const QString& key, const QImage &image); and if you want to see if it exists and retrieve it call: bool findInCache(const QString &key, QImage &image, unsigned int lastModified = 0) with the same key. so in your case, you may want to include things like the the view point and zoom level in the key. also, i'd suggest: * deleting the old image so the user doesn't end up with a bajillion cached papers (maybe i should add that bookkeeping into Wallpaper itself? Hmmmm.. yes, probably... "let me get back to you on that one," he says, again.) * putting a delay on the caching in case the user is moving around and zooming and what not.. you don't want to cause a bunch of disk caching to happen. maybe wait for non-action for 3-5 minutes or so? -- Aaron J.
