I have multiple custom icons for services in one of my projects. These icons don't show!

I thought at first they were just loading slower (not cached because I'm the only one using them), so I refreshed a few times.

When I inspected in console, I realized that the files are from my own server!

This means if my server is ever down (which it happens to be), I can't see the nice little icons I chose.

Suggestion:

Would it be possible for railway to store custom icons themselves? This could be quite economical (the images never really need to be more than 50x50) and it could even improve load times! (What if I choose a UHD image for all my icons across 30 services, now I have to wait for those to load!)
Also it would be nice b/c my dashboard would be prettier.
