jpg not opening

Can you help, I'm running Windows NT and all of a sudden i can't open jpg's.

the message i recieve is .JPG is not a valid windows NT application

right click and select "open with", you should get a box that allows you to select a program

select any image application you have (except for paint) and check the box with "alway's open files with this application" (or some text like that), then it will alway's open your jpg's with that program when you double click
if you don't have anything besides paint, use internet explorer

things like the usualy happen when you delete or uninstall the application that was responsible for the files (or MS OFFICE, they just love to f*** with you anyway)

there is also a possability you cought a virus that has corrupted your jpg's , although i'ts unlikely since it's been a long time since the latest virus of that kind (at least for win nt)

When i right click i dont get the option to 'open With'
