I saw in an earlier post that Karlis recommended 1024 x 768.  But is seems to me that most new monitors are "shorter and longer" - more of a letterbox format.  I want my screensavers to look good on the majority of monitors that people are using today.  My new laptop, for instance, has a 12 x 7.5 in. screen and the pixels would be 1280 x 800 to fit it.  Need some advice before I go ahead and resize/crop a whole bunch of images.  

  Thanks.
