images GIF and JPG

I DON´T KNOW WHY BUT EVERY TIME I RECEIVE AN IMAGE ON MY MICROSOFT OUTLOOK, IT APPEARED WITH THE WINAMP SYMBOL. HOWEVER, I CAN RECEIVE THE IMAGES ON MY HOTMAIL. I DECIDED TO UNINSTALL WINAMP BECAUSE I HAD A LOT OF PROBLEMS. BUT NOW, WHEN I TRY TO OPEN A GIF OR JPG IMAGE, I CAN´T. I HAVE TRIED TO ASSOCIATE THESE GIF AND JPG FILES WITH IEXPLORER (AS THEY ARE IN OTHER COMPUTERS) AND THERE IS A LEGEND THAT SAYS THAT EXTENSION GIF/JPG ARE ASSOCIATED WITH WINAMP.FILE. I HAVE DELETED ALL WINAMP FILES FROM MY COMPUTER. WHAT IS GOING ON? WHAT CAN I DO TO RESTORE THE SETTINGS AS THEY WERE BEFORE INSTALLING WINAMP?
