Hello Cybio.

1. Sorry.
2. When i'm typing a story, i can also add some pictures or videos. This is an option in wordpress right above where i'm writing. Then i'm clicking on tab "URL" and fill in the details, that's how i add some pictures, before adding pictures i'll have to add the pictures via FTP. So theres a map called "images" on my own server, nothing special i'll guess.

I'm not using any plugins or other imaging widgets. The gallery widget is the only widget i'm using.
