@Yusufbodrum - if you drag 'n drop the file - vob, mp3 etc - into the book list then calibre will create a new book. If you prefer to avoid drag 'n drop, and you're using Windows, put a shortcut to calibre.exe into your Send To folder and then use the Send to option from the shell context menu.

To add a non-book filetype to an existing book use the Add file to selected book option (Shift+A). You will have to change the file type selector to "all files" as it defaults to a list of book filetypes Ψ

You cannot store arbitrary jpg files in book folders. Only one .jpg is allowed which is always cover.jpg. You might be able to store other image types and have calibre 'know' they're there - maybe .tiff . When I want an extra image or two I insert them into the comments column. Beyond that I store them elsewhere and put some sort of link into calibre - today I would use a link to an Evernote 'note'.
