Uploading textures to be used for 3d model at runtime?

I have a project that I want the user to upload their own image that will be applied to a 3d model. This is going to be deployed for WebGL.

How do I upload an image, at runtime, that will be used as a texture on the albedo of a material for a 3d model?

I'm using the Simple File Browser from the asset store. The key parts are that this needs to happen at runtime, ability to upload the image to the server and apply the image to the designated material on the object.

As a note: I have seen solutions for Texture2D uploads, but it doesn't seem to apply to my situation. I have a tight deadline so any help or advice to understand the solution would be very much appreciated.
