Uploading / changing banner images

[ElStoko]

I have a banner stored at https://www.auran.com/trainz/GameFiles/images/Banners/3PCC This was uploaded (I think) using the predecessor to MyTrainz. Recently I have sought to change my banner image, but can find no way of doing this through MyTrainz. Is there an alternative way now of uploading/changing our banner images?

Go to your Setting page here at the forums, and click "Edit Signature". There, you can insert a new pic and write text as well to your liking.

The image used for a signature must be hosted so that you can point to it with a URL. I am using my Trainz banner hosted by Auran for my signature. I would like to continue doing this, rather than joining an image-hosting site.
So the point of my query is not how to change my signature's URL, but how to upload a new banner image that I will then use as a new signature. As I recall, Planet Auran permitted you to upload banner images, and this appears to have been discontinued in MyTrainz.
