For videos, I just clicked special BBCode, selected "media" and pasted the share url from sites like youtube, not the page url.

For pictures, I clicked the add Image button on the post edit toolbar and used the direct link.
Here you go!
I will look into the installer later and see if I can upload them for you.
Edit: I don't have San Andreas, so I can't install them to a folder. Sorry about that.
