Description

Dark images with transparent background are impossible to distinguish in image view, when tapping on the image to make it larger.
This is because the background is black, if the image is also black then the whole screen is black.
Similarly when using the dark theme, the icons of the sources are hard to distinguish if they are dark with transparent background.

For reference:
Dark image with transparent background in the article from 14/10/2021: https://ilblogdellasci.wordpress.com/rss
Source with black icon and transparent background: https://culturificio.org/feed

I can see two solutions:

Add a white background to images with transparent background
Invert the colors of those images, so that they assume light colors and become distinguishable

Both these solutions however would not work with an image with transparent background and light colors.

I guess the best way to handle this is to add a checkerboard background.
That is how images with transparency are normally rendered, the checkerboard solves the problem both with dark images and with light ones.
