    convert SMFPress.png -channel Alpha -threshold 80% -resize 120x120 thumbnail.gif

    This did a quick, same-size conversion with little loss for me to display the thumbnail online.  For more information on the options I used and other options that I didn’t use, take a peek at the ImageMagick Online Help Page for convert.

    head -n 96 filename.php | tail -n 1

    This allows you to quickly display the 96th line of filename.php. Hope this helps someone like it has me.
