Custom Kibana logo not appearing on certain machines

Hey! Not sure if this has been covered before (apologies if so) but I can't find anything that deals with this issue!

I changed the logo image in Kibana to a company logo, I can view this new image on my machine and all machines I have tested on, yet there is a user who can't see this image for some reason. On his screen there is no logo, only a black space where it should be. This is hard to test on my end since it works everywhere else, I was wondering if anyone knew of any reason why this could be happening or point me in the direction of a previous thread with a similar issue? Thanks in advance!

I can't think of a reason why this would be the case. What type of image is it? What browser is failing to load the image?

Thanks for the reply! It's an SVG image, and it was failing to load on Chrome originally. I suggested trying another browser and it then failed on both IE11 and Firefox!
