how to repeat a section of code changing file parameters

i have a section of my code that reads an image from a file in a folder, it then processes that image and gives an output... i want the code to change the image file name at each cycle. for example; if image name is "image_1" it should then change to "image_2" and so on... this is the section of code so far:

    % code
vid = videoinput('winvideo', 1);
set(vid, 'ReturnedColorSpace', 'RGB');
img = getsnapshot(vid);
pause(1.5);
imshow(img);
%// this is where image is saved
counter  = 1;
baseDir  = 'C:\Users\Nakk\Documents\zvanhasi\Number_Plate_Extraction\';
baseName = 'Image_';
newName = fullfile(baseDir, sprintf('%s%d.jpg', baseName, counter));
while exist(newName,'file')
    counter = counter + 1;
 newName = fullfile(baseDir, sprintf('%s%d.jpg', baseName, counter));
end 
imwrite(img, newName);
%and then this is the part that reads image from file and process it
f=imread('Image_1.jpg'); % Reading image file.
%then some processing steps

so i want the

f=imread('Image_1.jpg');

to change to f=imread('Image_2'); f-imread('Image_3');

and so on....

end

hie thanks azzi but it didnt seem to work... i need the code to change each time i run it, the loop is just displayin " file = (Image_1)..." up to 10 in the command window...

I've inserted %do. replace it with your own code
