but when I try to save only 1 or 2 or 3 its throws an exception "Empty Path is not legal".

Hi suman, when you try to save 1 or 2 or 3 images it throws exception because, filestream requires the path of the file and it should not be blank or null. **Syntax****FileStream(string path, FileMode mode, FileAccess access);***** In your case, when you dont save anyone or more image, the path is set to blank i.e either your picLoc or picLoc1 or picLoc2 or picLoc3 is blank check for empty string or null string in your code and save accordingly

While saving the image the path is null or empty it seems. Just debug & check it for empty & null.

hi suman, before reading file, i.e FileStream fs = new FileStream(picLoc, FileMode.Open, FileAccess.Read); i.e if(picLoc != null && picLoc != "") { FileStream fs = new FileStream(picLoc, FileMode.Open, FileAccess.Read); } check whether the path is not null And not empty If path null And empty, then dont read the file. same for other image path also. try it, and let us know
