Hi,
I've updated my website to 2.10.3 and had to downgrade to 2.10.2 immediately since with 2.10.3 any image from JoomGallery is no longer loaded inside articles.
Normally I put images via the plugin inside my articles which worked fine:
www.joomgalleryfriends.net/downloads/download/18-plugins/303-content-plugin-joomplu.html
With 2.10.3 the popup still works however the thumbnail images are no longer loaded.
With 2.10.2 everything is fine.

Joomla 3.9.18
Gantry5 5.4.34
PHP 7.3 stable

Have a nice sunday and thanks for the great component!

I've tested 2.10.4 dev on my testing webspace and JoomGallery pictures are loaded again within articles.
So I'm waiting for the stable 2.10.4 to install it - obviously there is a difference between a kind of bug in 2.10.3 and 2.10.4 dev.
Thanks for your work and effort!
