Confluence Insight plugin - broken icons

[Samuel Carter]

We have Insight set up and working nicely. I am using the free Insight plugin for Confluence to render out some IQL queries. Whilst it displays the data correctly, I notice that it won't display any of the icons we've chosen for our Objects.

Icons display fine whilst in Insight, but when rendered out using the Insight plugin for Confluence, it displays the generic 'broken' thumbnail instead. 

Any solution to this issue?
