My original pictures are 3264 x 2448 or thereabouts. Initially I reduced them to 640 x 480 but I am wondering if they might load too slowly for folks with slow machines. I want the, "click on's," to be as large as practical. On my "morephotos-2," page of "dabsoflight.com" I have most of them reduced to 2oo in "pixsizer." But except for a couple on the bottom row that click a larger size that I prefer, I wonder if the others really need to be as small as they are. The presentation size is fine, It is only the pick size I am concerned about and the speed of viewing.
