How do you delete an image added to a "user" image page

[Ripper1302]

I added a user's image that used a mod's feature to that mod's page late last night. The image was too small for easy viewing so I added an larger version of the same image. I now have two user images on that mod's user images page. I want to delete the smaller image. How does the poster of a "user's image" delete an image they posted to a modder's page?

 

Thanks for any help.

They don't, the author would have to remove it.
