Please fix the downloadable picture issue

I’m getting tired of this. I check out something like a map. I click on one of the pictures to see it bigger, and it says I can download it instead of going to a new page so I can see the full-size version of it.
Is there a way to configure Firefox to fix this? Or is this because of the site?

Yeah I’ve been having the same issue with only the gmod download page, the forums work fine. I’m using Firefox as well and have been unable to find a solution. Any help would be appreciated.
