I Imported a human model but its texture are not appearing on the model?

I have a general question if anyone can answer, if you were to find a human model on the internet, download it and import to blender, but there is no texture appearing on the model even if it has a texture file. What I wanted to know is how can I do this . If answer thank you.

You should share the model/link otherwise we can only guess what’s wrong.

I found the solution now. its using image texture within the node materials. Thank you for coming forward
