Right click on the jpg file, properties, change the "open with" property to Internet Explorer & try.
If the jpg image is not corrupted, it should open with IE.
I reccomend you to install IRFANVIEW (Freeware) for viewing images.http://www.irfanview.com/
If you have antivirus run a full scan in the system & Check for threats.
Also download & run a scan with malwarebytes for trojans/malwares, which also may cause file corruption.http://www.malwarebytes.org/
