I am trying to add a popup image to image_popup.php for my PurpleAir block. I have added
$n = 'aqichart';
$pop_img[$n]['url'] = '../aqichart.gif';
$pop_img[$n]['txt'] = 'aqichart';
$pop_img[$n]['head'] = '';
$pop_img[$n]['show'] = 'other'; # to avoid vertical stretch
but all I get is the ‘earth’ popup (Map popup in Sun block).
For $pop_img[$n]['show']
I have tried ‘frame’ and ‘other’ and nothing at all, with no success.
What am I doing wrong?
The popup should be called with
https://swanston.maui.co.uk/pws/image_popup.php?nr=aqichart
The “earth” pop-up shows in this case as the aqichart is unknown in the image_popup.php script.
When I check the source I do not find any text with aqichart
https://swanston.maui.co.uk/pws/image_popup.php?sce=view
Where did you add that text into?
Wim
I saved image_popup.php into …/_my_settings 
That is what I was doing wrong 
Thanks, Wim - again 
LATER EDIT: I have to say I get confused with PWS_frames.php, frames.php and image_popup.php
