I've had no problems to insert local images in my reports, however when it's a dynamic image I can't get them to appear.
In our database the image object (in reality a string in the DB) is something like this,
/pluginfile.php/1/block_m4m/center_logo/14652/logo%20color.png
that when coupled with a string including our enterprise url it appears in the webbrowser, however I can't manage to make it work with the options "Image URL", or "Data Column", available in the program

Any clue?
