Greetings, I need to find the Mime Type for a PX File. I’ve been through several on line lists but have found nothing.
Suggestions?
Thank you!
Wow, ralph, that’s a better site than the one I usually go to for looking up file extensions! Thanks for posting it.
Hi irishf, welcome to SitePoint! 
I’ve never even heard of that, to be honest, but a quick Google offered up this page:
Where is says
MIME type: image/px
May or not be of any use to you!
