Hello Bernd,
Adding the image meta data in the image URL is indeed a feature which was discussed in great details
here.
I wasn't aware that you no longer can delete the image meta data (the solution shown in the other discussion).
As a result, I would expect that with a Joomla 4 template that is equipped and delivered with various Gantry 5 Particles, these will then also work error-free and without any action on the part of the customer.
You are right to expect those things, and the last couple of days I was trying to find a solution but I couldn't. I will explain why...
As you know, our particles use the
Gantry 5 API to fetch Joomla article content.
Unfortunately, the Gantry 5 API does not offer a method that will clear the Image URL. Therefore there is nothing we can do.
To give you more context, the attached screenshot shows the code in the "Content PRO (Joomla)" particle that is responsible for fetching the Image URL. There is simply nothing else that we can replace this code with, so we can get the clean Image URL (without the meta data).
The only workaround is to either disable the Lightbox functionality or to use the "Content PRO" particle (not "Content PRO (Joomla)") where you enter all the data manually.
