Aspect ratio of pictures is not perserved on display size change.

[hisbaan]

Describe the bug
The aspect ratio of the images next to articles and feeds in ArticleCard and FeedCard do not have a constant aspect ratio on different size phone screens. On one phone, it may be square, while on others, it can be a taller rectangle.

To Reproduce
Steps to reproduce the behaviour:

1. Get a phone with a taller aspect ratio that has a thinner aspect ratio than 2:1.
2. Open the application.

Expected behaviour
The aspect ratio should be consistent across all devices

Screenshots

Wider aspect ratio:

Notice that neither of these two have "square" images as is intended. One is too tall, the other is two wise, running the same code base.
