Profile icons not displayed in html/pdf export's comments area

[Doris Tam]

When exporting a portfolio with 'Include comments' switched on, we expect to see the profile icon of the account holder who had made the comments. If the account holder customises their profile icon different from default placeholder, the thumbnail appears broken on the export.

Steps to reproduce the bug:
- customise your profile icon
- create a portfolio page
- add a page comment
- export the page
- check the HTML/pdf

Expect: to see the profile icon
Actual: broken image

This bug also applies to artefact comments where feedback given by the portfolio owner and replies by other commenters have broken images displayed as their customised profile icons.

I'm not sure if it depends on the filetype, however, I know that PNGs doesn't appear on exports.

Please also test with JPG.

After discussing with Kristina, there are three ways of approaching the export of comments.

Context: Profile icons do not add value to the export comments, they're an accessory.

1. Show the custom profile pictures
2. Use the default profile picture in place of custom profile icons
3. Don't show icons at all when exporting comments
