How to plot many images in a loop

Hello,
I am working with a Matlab code where I want to run a loop. In each loop, I will do some processing and then show an image based on the processed data. When I go to the next loop, I want the previously stored image to be closed and generate a new image based on the latest data.
A sum up from my code is this :
for ww= 0.4:0.2:2.6
**********************image processing code*********************************
t1=1-ww*(dark_channel1/A); % part that connect ww with the image processing code
**********************image processing code*********************************
out = pic;
figure;
imshow (out)
imwrite(out,sprintf('%d.jpg',ww));
End;
What I expect is many different images depend on the "ww", but the output that I take looks like in each iteration each image sticks to the previous one.
I think that somehow I can’t separate the output (image), and after each iteration I don't reset my loop. As a result I display a new image but stack on the previous. It is like in each iteration the new image sticks to the previous.
Any suggestions??
Thank you in advance

for i=1:5
imwrite(randi(255,250,205)/255,sprintf('Image_%d.png',i))
end

Regarding your email:
There must be a way to reproduce this problem. Try removing code line by line to see what happens when.
As an example:
for i=1:h
for j=1:w
dark_I(i,j)=min(img(i,j,:));
end
end
This sets some values to dark_I. Assuming img contains integers 0-255, you can replace this loop with this:
dark_I(1:h,1:w)=uint8(randi(255,h,w));
It is also possible to create a mat file containing dark_I wrapped in a cell with the values for the first 3 iterations. That should also be enough to replicate the result.
I don't do private consulting, there are other people you can hire for that. You need to find a way to reproduce your issue in fewer lines of code than you posted above. Unless there is a bug caused by a very specific condition (making it hard/impossible to reproduce on my end anyway), it is almost always possible to reduce the cause of such behavior down to code that fits on one screen.
