JPG Association

When I try to open a jpg file I get an error saying there is no association for this file type & what program do I want to open it. I pick explorer & the file opens but when I try to click on the option at the bottom of the box that says "always use this program to open this file type" its greyed out. I'm assuming there must be a regisrty fix for this, but cant find any information about this type of problem (I've had a look at the local security policy & cant see anything in there for this option) I have logged into the box with admin rights.
Any suggestions would be greatly appreciated. Thanks

What program did you used to use to view images?

 

I used either internet explorer or photo shop, both opened *.jpg files successfully but I could not save this so that next time I went to open a jpg file it would automatically.
