petero82 Ok, so basically you want to achieve folders listed with large preview images (like normal image thumbnails), instead of the folder icon, correct? I have had a couple of requests for this, so I will look into an official solution for next release.
A few things were not clear:
petero82 My question:
Is it possible to change the folder view like it is shown in the following screenshot?

This is from Synology photo station? If you are referring to the thumbnails with large preview images, then yes it could look similar to that. The other layout elements (menu, breadcrumbs etc) won't look like that of course. There are a couple of issues in regards to this layout:
- How does the user know they are clicking a folder and not an image? There is no clue on the preview. If you are mixing folders and images int he same dir, the user can't possibly know if they are clicking an image or a folder. I personally don't have a problem with this, but it's definitely worth mentioning.
- Unlike the above, Files Gallery has many different layouts, each where grid elements can be resized. Some layouts will show the folder previews square, and possibly very small, limiting the title length.
petero82 The actual folder view in files.gallery looks like:

You mean you managed to achieve the above, but you want it to look more like the first screenshot? Keep in mind, in the above screenshot, you have selected GRID mode, so it will definitely not look more like the first screenshot until you select the ROWS layout. Other than that, basically you want the titles to overlay the image? That's the only difference I can see ...
petero82 I wanted to have that style of text, but also the text inside the folder changed.
What do you mean "text inside the folder changed"?
petero82 I only want to have the changes in the folder view, not in the folder.
You mean you want your changes to ONLY affect folders, but not images? If there are folders inside the folder, then obviously the folders inside the folder will also get affected by the style change.
