I used to have this problem...When I took a pic, the pic would be 1 or 2 mb and would reduce to 500, 600 or 700 kb after I'd cropped them, still gar too large. What I started doing was taking the pic of the item from quite a distance back, about 3 or 4 ft away and then cropped it and sure enough, pics would come out at 80, 90, 100kb a pic.
