[Frontend] SEO / SEF Configurations

[DevelPott]

I'm sure this will come, but I've noticed it.

1. The display of the categories is not yet like before
   So far it was like this: domain.de/gallery/category
   Now it is like this: domain.de/gallery/3-category

2. In the detailed view, the URL of the image is not yet speaking: www.domain.com/gallery?view=image&id=17

3. The alias of the image is a number (numbering) and not an alias generated from the image title.

4. Also, the title of the image is not the same as the title of the page (<title> + browser title)

5. The description of the image is not the same as the meta description

Thanks for your great work. Danke
