Extracting files saved in .mat file

I have saved a set of images in a single .mat file and also generate a txt file contains the filenames of the images that have been saved in the .mat file. I am looking to be able to extract the images from the .mat file. Any help would be welcome. I have attached the code here.
function saveimage()
[fname,pname] = uigetfile('*.*','Pick an Image File','MultiSelect','on');
if isequal(fname,0)
warndlg('Program has been exited without any files being selected','!! Warning !!');
return;
end
if ischar(fname)
fname = {fname}; % If a single image was selected
end
k=0;
l = length(fname);
for i = 1:l
currentimage = imread([pname fname{i}]);
imgs(i).currentimage=currentimage;
fprintf(fout, '\r'); fprintf(fout, fname{i});
k=k+1;
end
save([foutpath num2str(k),'_',num2str(dt),'_Images.mat'], 'imgs');
if (l > 1)
message = sprintf([num2str(k) ' images successfully saved\n\nResults are saved in ' strrep(foutpath, '\', '\\') '\n\n Click OK to continue']);
uiwait(msgbox(message));
else
message = sprintf([num2str(k) ' image successfully saved\n\nResults are saved in ' strrep(foutpath, '\', '\\') '\n\n Click OK to continue']);
uiwait(msgbox(message));
end
return

You should be able to load the image matrix into the MATLAB workspace using the LOAD function.
var = load('filename.mat');
As per your function, var would most likely be a structure array and the field 'currentimage' would correspond to your image file which you can then write to an image file using the IMWRITE function.
imwrite(var(1).currentimage, 'filename', '<format>')
I would recommend reading the documentation on LOAD and IMWRITE.

Hmmm... Looks like Ram needs to look at this so he can learn how to see what's in variables: http://blogs.mathworks.com/videos/category/gui-or-guide/
