Display files via mini front page PRO

1. You have built in a copy for me to choose from for all themes, where is the difference to the original themes, or are they just a secured template?

You can compare these two files to see the difference :
- /modules/mod_minifrontpagepro/tmpl/carousel.php
- /templates/your_template_name/html/mod_minifrontpagepro/carousel.php
There's a technique in Joomla to override the module output layout. This technique called template override. You can do that by copying the layout file from the module to the html folder inside the template folder, then modify the code. That's what I did to your website before. This technique is an update-safe technique, because when you update the module later, it will only overwrite files inside the modules folder, and the file inside the template folder will remain unchanged.

2. In the category overview (under the item "News") I would like to use the theme "infinity!" I would also like to remove the link from the title and the image, unfortunately I do not get the carousel code in the corresponding php file changed.

I have modified the file /templates/your_template_name/html/mod_minifrontpagepro/infinity-ajax.php and removed the link from title and thumbnail. Please try.

Oh, I just saw that the content at infinity is now available twice, once the correct one (with a link) and a second the pure text ...
