Feeding the beast....  I believe it's a matter of almost constantly uploading... I upload 3 or 4 images, 2 or 3 times a week( ie. constant). I suppose it's a matter of what total number of images you have to upload. If you put all 450 up in one shot... then you're done until you create new ones...  therefore, the more you upload in a batch, the sooner you run out of material to upload to SS.  If you are generating 15 new shots a week, then you can continue to feed the beast...
   how's that for talking in circles?  some pretzel logic there, hunh?  =tom
