Remove empty information fields for Flash Update Export and make image bigger or clickable

[toffehoff]

Is your feature request related to a problem? Please describe.
When you share a Flash Update with a donor, they will get an email with a PDF in it. Same PDF which you will get if you export a Flash Update. This PDF also shows empty fields (which are not shown in the Flash Update online).
The attachments shown (image and graphics) are shown quite small. This does not help the readability of these graphics/images

Describe the solution you'd like
Only show fields that contain information. E.g. When there are no actions taken by the RCRC, then do not show that section (instead of saying "none").
Also, the image added is only shown quite small. Can we either make this bigger (so the map is actually readable), or you put a link on it so you can open the original one in a browser.

Describe alternatives you've considered
Continuing our current working model: not using Flash Update, but generating an Info Message which the HDCC department sends out themselves.
