Substitute "[Download File]" for pathname?

Hi, this seems like it must be a no-brainer. I feel like I have no brain because I can't figure it out!

I want visitors to the node to see "[Download File]" instead of the full filename to click on for download. This must be an incredibly basic thing I'm missing. I know how to do substitutions in Views, but I just want it to be this way in the node itself.

Here is a sample page at: http://www.theresistancefit.com/news/todays-woman-enterprise

Also, I had to create a snapshot of the file myself in Photoshop converting PDF to JPG, is this something that can be done automagically?

Thank you!
