I've been trying something different as of late and it has worked pretty well. I will take a bunch of chips and place them on the scanner bed (alignment or position is arbitrary). I scan it at 200DPI. This does produce a pretty big file (upwards of 10.5MB for 20 chips) and then using Adobe Photoshop will cut each chip (with the fixed circle tool).

Then I rotate the cutout correctly and cut the picture again. This is saved for checkmate and then the image is reduced to 100dpi for the web site and saved as a JPG file.

Most of these steps can be done with Photoshop actions chained together based on pressing a function key.
