Here are a couple of Unix commands that may help you get your images in a standard format for this page:
To rotate files in unix 90 degrees clockwise you can use jpegtran.
jpegtran -rot 90 Jeff.JPG > Jeff.JPG
To get a standard screen crop I was using Picasa to do a 4:3 crop (instead of a manual crop) and then saving the image and resizing it.
To resize the image to 200×150 you can use convert.
convert -size 200x150 Jeff.JPG -resize 200x150 +profile '*' Jeff200.jpg
If you would like me to post your picture and details, feel free to email me a pic and your homepage address. — Jeff Long
