What do you mean "show all jpg images" ? If you have a thousand images, displaying them all at once could be a bit bewildering.

Yes, it may be. But still I want to know how can I do this?

This displays all of the jpg images in the current directory:

S = dir('*.jpg');
for k = 1:numel(S)
    figure();
    image(imread(S(k).name))
    axis('image');
end

Note: this code will not work with indexed image formats.

Perhaps one of the submissions creating thumbnails (into tables guis or the like) found on the file exchange does what you want: Thumbnaily submissions

(Almost) straight from the docs for montage:

% Create a montage from a series of JPG images in a directory

targetpath = fullfile(matlabroot,'toolbox','images','imdata','*.jpg');

imds = imageDatastore(targetpath);

montage(imds);

Alternatively, without using imageDatastore():

% Create a montage from a series of JPG images in a directory
targetpath = fullfile(matlabroot,'toolbox','images','imdata','*.jpg');
S = dir(targetpath);
allpaths = fullfile({S.folder},{S.name});
montage(allpaths);

In either case, if you want to actually save the output to a new image file, don't use montage(). Use imtile() instead and save the result using imwrite(). Most of the syntax overlaps between the two, so it should be fairly straightforward.
