I have tried analyze75read command, but getting errors, may be because i dont have .hdr file. But basically this is the medical image dataset which I downloaded from an authentic site and there is no .hdr file avalaible even I saw on some other sites, but everywhere medical images are stored in .img format so there must be some way to use it. Below is the link of my .img file. http://1drv.ms/PQdIox I will be thankful If anyone can help me out.

fid = fopen('fileName.img');
data = fread(fid, dataDimensions, precision)
close(fid)
for more info:
doc fread
doc fopen
And use imwrite to save it as jpeg.

.img files are not image files that are handled by imread(), and they are also not just plain binary files as hinted by Dishant.
.img files can be produced by Analyze; for those see http://www.mathworks.com/matlabcentral/answers/71339-how-can-i-read-or-open-a-img-file-using-matlab
.img files can be DICOM files; for those see dicomread()

Perhaps you could use dcm_unconvert to recreate the dcm file that could be read with dicomread()
