Hi Marek, 

currently, a single function composes this output. To change this, you would need to modify the template. Are you familiar with template overrides? The $file-object contains a couple of methods to retrieve what you want to display, and you can wrap them into the desired HTML-tags.  

To simplify the template override (and to reduce possible errors in future versions with template overrides), I refactored the template structure and added some methods for you to retrieve data. You need to download the latest build from there: 

Download (svenbluege.de) => https://www.svenbluege.de/joomla-event-gallery/eventgallery-download/event-gallery-bleeding/eventgallery-3-12-9/pkg_eventgallery_full_3_12_9_20210808074843_d2128945-zip?format=zip

Then you have a new file components\com_eventgallery\views\singleimage\tmpl\default_image_description.php

This code will output the necessary data, please wrap it with the HTML-tags you need: 

<?php

echo $file->getFileTitle();
echo $file->getFileCaption();
echo $file->getFileName();
echo $file->getExifAsString();

?>

For a start, you can directly modify the default_image_description.php file. If it works for you, I recommend creating a template override. This will avoid losing the changes with every Event Gallery update.

Please consider testing on a copy of your site to avoid any issues with your production site.

Very nice! I'll include this change in the next release. Make sure you're using a template override to avoid losing your changes.

What is the path and filename of your override?

Try TEMPLATE\html\com_eventgallery\singleimage\default_image_description.php

the /tmpl is not necessary in the path.

The file needs to have exactly this path: TEMPLATE\html\com_eventgallery\singleimage\default_image_description.php I tried it a second ago. You can also use the Joomla template Manager to create the override files. It will create too many files, so delete what you don't need.
