Describe the bug
When viewing images that are longer(H) than the device screen, fritter will fill the whole width of display with the image, but cut off other parts of the image.
Even with zooming out, it reveals that the image is limited to the screen size.
It would have been fine if fritter simply tried to fill the whole screen and I could zoom out, or if the image was fully displayed and I could zoom in. (Optimally it being setting)
It is strange to display the whole image in the feed but cut off parts when looking at the file in full screen.

To Reproduce
Steps to reproduce the behavior:

1. Find a tweet with image attachment that is longer(H) than your screen.
