Obscene Images from unsplash.com at NextCloud

Sometimes we get obscene images as nextcloud login /download background pictures, is it possible to filter such images?

With the unsplash random image url we can not spcify what should not be on the image.

But maybe we can fetch the image from https://source.unsplash.com/featured/?nature,wallpaper. This is also random but from their featured collection (and not all images) and those seem to be more sfw.

That is most unfortunate!

I will have to look at the api, but it seems they have a filter for that:
https://unsplash.com/documentation#content-safety

you can try to edit the url to your liking if you have write access to the appdir

@newhinton this param wouldn't work because it's from the Unsplash API, and this plugin uses the Source API: https://source.unsplash.com/

It seems that the URL is already trying to get an image from the featured images:

unsplash/css/login.css

Line 4 in f77d642

background-image : url('https://source.unsplash.com/random/featured/?nature') !important;

But the API is used incorrectly. random shouldn't be in the URL, and therefore images aren't only those in the featured collection.

Here's a demo (note: I appended daily to all links in the demo to compare the results together):

The following URL will return the random daily image from the "featured" collection, with search param "nature": https://source.unsplash.com/featured/daily?nature

With random in the URL (https://source.unsplash.com/random/featured/daily?nature), as it is at present in this plugin, the image isn't the one from the featured collection, but from the broader random daily image: https://source.unsplash.com/random/daily?nature.

In short: with the current URL, featured is ignored, hence the unwanted images.

@robinmetral Sadly, i cannot replicate the issue (due to the random nature of the issue). However, i have confirmed that your changes are working, therefore i will give it a try and i will release it.

I prepared an release which should pop up soon in your instances
