Hi, I checked your auction, I'm on cable and it loads beautifully. Very nice listing.
I'm not sure either what watchinu means by "dpi" (dots per inch). Usually you go by pixels, like your photos come out at 900x1200 pixels.
Auctiva only resizes the pictures that are actually on your listing, but if someone clicks on them, it loads the original sized picture (bigger) so it's more detailed.
