As discussed, this deals with the code duplication introduced in #260.…

… These changes aimed at generelizing the

approach used to introduce media types to the project. Images and videos now use a method called
_make_media_html_div which generates the media div in a streamlined manner. Both _append_image and _append_video
use this method, to which they can pass their base string and class.

Unit tests were left untouched, as the changes only affect private methods.
