Icons on a server were made in 16x16, but now I see them upscaled to 20x20 on my new computer, also on a Mac, it is 32x32.
When I set a 20x20 icon on the server, I see it with no modifications, but others see them in 16x16 (downscaled). And they have the same screen resolution ! Can I put an option on my server for every icons to be displayed the way it was made or does it completly depend on operating system and screen size ?

The problem is my 16x16 icons now appear blurry. Thanks for answers
