Bulk Resize Images

From http://www.novell.com/coolsolutions/tip/16524.html

mogrify -resize 320x240 *.jpg

After this command is completed, all of the images will be replaced with resized version of themselves. Notice that in an effort to preserve the image aspect ratio, mogrify may not be produce images that are exactly 320x240. To force this to happen, modify the original command to by placing an exclamation point at the end of the desired resolution:

mogrify -resize 320x240! *.jpg

Installing an Epson Perfection 1670 Scanner

From Ubuntu Forums

HOWTO: Epson Perfection 1670 Scanner

The scanner firmware comes in a file called ESFW30.BIN, which apparently is only available if you install the software on the CD-ROM provided with the scanner. Unfortunately, the software only installs under Windows and then you have to copy the software from the Windows machine to the linux machine. Or you can follow this simple process to download the firmware (provided by Jeff Silverman) and then update your /etc/sane/saned.conf

$ wget http://www.commercialventvac.com/~jeffs/ESFW30.BIN
$ sudo cp ESFW30.BIN /etc/sane.d

Edit /etc/saned.d/snapscan.conf and change the line...

firmware /path/to/your/firmware/file.bin

...to point to /etc/sane.d/ESFW30.BIN

$ scanimage -L

You should see that your scanner is now detected. If so, you can now scan using XSane.
