Not all images are displayed with Firefox

Hello Evan,

Now that I have solved compatibility issues with the Fidelity theme, I have a new issue, only with Firefox (latest version). Some announcement images are not displayed, instead there is this character string: “Announcement Image“
I have tried all sorts of tests (regenerating thumbnails, changing images, deleting the entire list of announcements, reinstalling the plugin …) and nothing works. Actually the issue seems related to the position of the announcement in the timeline more than which announcement (tested by inverting the display order).

Curiously there is no problem with Chrome, Edge or Safari (iPad). This is a Firefox issue only. Clearing the cache does not help.

Here is the link: https://www.fondaphotos.com/timeline/

I forgot to mention, I have created a child theme and included the filter you have provided to display images in full size. It works very well most of the time.

Could you have a look please?

Cheers
