Hello ToshaZabka
My name is Fred. I am an independent advisor, First of all, thanks for being part of the Microsoft Community, I will try to help you.
Where this happens on the browser when you save a picture?
Even if you have never edited your registry before, following this step-by-step is as about as sure-proof as you can get!
>>Click on the start window in the bottom left of your screen.
>>In the search bar, type regedit and hit enter. (May open the registry app or a small window)
>>Click YES on the pop up window.
Find the following route:
"\HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/jpeg"
>>Locate the word EXTENSION and double click on it.
>>A box will pop up and will say ".jfif" for the Value Data. Erase that and type ".jpg"
>>Hit Okay and close the window by hitting X in the top right corner.
I hope this information is useful to you.
Best Regards,
Fred
