Dynamic image in report 7.9

Trying to insert an image into a report, the image (a screenshot of a boxplot from a vision client) is captured by a script and inserted to SQL server as a varbinary (I searched for blob and apparently this is the modern day equivalent?).

How do I then get this inserted into a report? Tried doing a select from DB query, and dragging that datasource to the design, I just get a single “a” character displayed.

OK after a nights sleep and despite reading the manual yesterday I read it again and have it working (drag the image datasource to the key property on the image component).
