Good idea. Other Debian based distros have started with the project
logo, a screenshot feature would be nice.

I would think maybe a command like 'apt-get screenshot <pkgname>'
would be good, so Synaptic/KPackage/etc. can have a 'show screenshot'
button which would execute apt-get screenshot and then display the
image from /var/lib/apt/screenshots/pkgname.jpg.

That would be good as well, it would allow instant display of images
for every package.

Where did you get that number from?

Also depends on the compression level set. There could even be several
different sizes you could download by passing an option.

Depends how major that new release is.

Yes. I would think though that the project logo could be included in
the package and screenshots downloaded externally.
