The reporter plugin already have a very cool feature {{issue.description | with_formatting}} that format a text field.
See: https://www.redmineup.com/pages/help/reporter/text-formatting

Unfortunaly when we have a image refered in the midle of the text, that image is not managed automatic.

We request that {{issue.description | with_formatting}} should deal with inline imagens similar to default PDF export supported by redmine!
