[SOLVED] Is it possible to delete custom icons?

I uploaded a custom icon which appeared to be OK when viewing on my laptop. However, after uploading to the web configurator I realised it wasn’t centred. I can’t see an option to remove it though.

Under Settings → Ressourcen just klick on that icon then a red delete icon should appear

That’s done it! Thanks @Freshhat. I was looking in the same screen where you can select and upload them.
