I can not read Harvard Mediacl School MRI images which are in .gif format.Whenever I tried to read by using imread() and show it using imshow() funcions, the images are not appearing as it is seen in the webside or in desktop.Two images are included here with the attachment.

yes,sir,may be check the map,use
k = 1;
[im,map] = imread('https://ww2.mathworks.cn/matlabcentral/answers/uploaded_files/916049/1.gif');
if ~isempty(map)
im = ind2gray(im,map);
end
imwrite(im, sprintf('%d.jpg', k));
figure; imshow(im, []);
if use loop to prcess 310 images, may be use
% total 310 images.
for k = 1 : 310
[im,map] = imread('your image file path');
if ~isempty(map)
im = ind2gray(im,map);
end
imwrite(im, sprintf('%d.jpg', k));
end

In your prior comment, you asked about avoiding quality loss. If that's still your concern, do not use JPG to save the image.

Save it as png file and open it
data = imread('1.png');
imshow(data)

See the FAQ
Inside the loop call imread() to read it into a variable, then change the file extension to PNG and call imwrite().
