If you have imagemagick installed, then you can put the following alias into your .bash_profile. It will convert every png in a directory to a jpg, which automatically removes the alpha. You can use the resulting jpg files as your screen shots.

alias pngToJpg='for i in *.png; do convert $i ${i/.png/}.jpg; done'
