Atari ST transparent file compression
This is an excerpt from the AtariSTPlusPicView.txt "readme" file, from the Atari ST Plus Picture Viewer v1.15 software by Ben Jos Walbeehm:

Compression was used very often on the Atari ST and in a more elegant way than giving the files extensions like .zip, .rar, .7z, .cab, .gz, .z, and so on. When an image was packed/compressed, it often kept its own extension. So if a file called "image.tny" were compressed with some packer, the resulting file would still be called "image.tny". If the system had the correct tools installed, this would all still work. Those tools would unpack the file transparently to the user. On a PC, this would be like zipping a file called "example.txt", calling the resulting file "example.txt", and having it unzip automatically and displayed in Notepad (or whatever other text editor) when opened.

So there are quite a few Atari ST pictures that you can download from the internet that have been compressed by some external packer.

It lists some examples: Atomik Cruncher, LZ77 (ray/.tSCc.), Pack-Ice, PowerPacker, SpeedPacker, StoneCracker, and Turbo Packer.
