Add support for all images in media content

[LaChope]

@blcham
SForms only support google drive "preview" links for images in media content. Support should be extended to all images, even outside google drive, with possibility to click on image to open the source in another tab.

We have 4 different options:

1. real image (we support it but do not keep the ratio)
2. real video (we don't support it)
3. frame (we support it and proportions of image are kept)
4. custom URL (e.g. https://drive.google.com/file/d/1ItZqsUm82nKW4ZqvKaiGUn202NEF79FC/view?usp=sharing)

Right now the different medias are displayed vertically, wouldn't be better to display them horizontally?

No because, we want to support mobile interface.

• images & vidoes (** taken from media type of a request**) --> show it in SForms way
• images from google drive:
  • view --> preview
  • preview ---> ugly gray stuff
  • export (https://drive.google.com/uc?export=view&id=[image_id])

Google drive videos don't work in anonymous tab

This is the issue:

The issue is that in incognito mode third-party cookies are not enabled.
