Scott, have you noticed any difference in the end result (using Photoshop) 
between reducing dpi and then resizing versus just resizing in one step?

  Dave,

  I personally scan at a much higher resolution (300/600/1200 dpi) than I 
ultimately use on the web. Scan, perform whatever corrections/retouches/etc. 
you desire, then reduce for the web. Since I happen to use Photoshop, I first 
reduce to the resolution I want (usually no more than 96dpi), holding size 
constant. Then I reduce the size to whatever I feel is appropriate (but often 
640x480 to accommodate those with small monitors).

  A rule of thumb: A monitor set at/near 640x480 is typically about 72dpi, one 
handling 800x600 or higher is typically at about 96dpi.

  Final step is trying to decide how much compression, if any, is bearable when 
saving as JPG. That's often a function of both one's software and the 
photograph itself. Photoshop seems to do a good job of applying compression in 
JPG format while remaining free from artifacts, some others do not. Also, 
photos with lots of "sharp breaks" between colors/tonal values often seem to 
exhibit compression artifacts under less compression than those with more 
smooth gradations.

  All of this is much simplified, but boils down to this: through the entire 
process you are trying to balance "good aesthetics" with speed of download. The 
higher the resolution/larger the final image size you choose, the larger the 
image file will be and the slower the download (and therefore the less likely, 
for most general web purposes, that someone will wait for the picture to be 
displayed).

  HTH, and I'm willing to bet others will have much to say regarding my 
particular choice of procedure. :-)

    What scan rate are most using for TOPE?  If I scan a photo at much over 
    100dpi it is too large to see on screen.  I am still pretty ignorant as to 
    how to overcome this issue, but when I look at some of the new photos in 
TOPE 
    5 I am jealous.  I am especially struck by how sharp #22 is.  My submission 
    is as sharp in the original photo, but loses something in the scanning.  
Any 
    input would be appreciated.  Thanks.
