I was having Microsoft windows SP2 operating system but few days back due to virus problem I formatted my system. I am having Mac osx operating system installed on my system. The problem I am facing is of JPEG file. When I open my email account any download any JPEG file from my inbox it displays an error message saying that it cannot open the file because it is damaged or corrupted. I cannot understand that whether Mac osx supports JPEG file format. Suggest some opinion to overcome this problem. Also some tips for opening and saving file in Mac osx.
