size of screenshots is huge!

[jfix]

[This might be a duplicate of #14]

Me again. I've noticed that screenshots taken with manet are huge, size-wise. For example, the Google homepage, as a screenshot is about 3 MB in size (see screenshot of the screenshot below). Others go easily to 8 MB and beyond. manet was started like this:

forever start -a -l ~/manet.log -o ~/manet.out -e ~/manet.err /usr/local/bin/manet --port 3000 --engine phantomjs

In comparison, screenshot-as-a-service (from here: https://github.com/fzaninotto/screenshot-as-a-service) produces screenshots of only a couple of hundred kilobytes, and their quality are comparable.

Any idea what I could change to decrease the size? I'm using the option quality=0 but that hasn't had any impact on size. I've also tried changing the engines (phantomjs vs slimerjs) but I don't see a difference either.

Thanks for your help in advance.
