How to combine blocks of image into single image?

I have divided an image of size 256*256 into blocks of size 32*32 and changed the pixel values.Now I want to join this blocks with changed pixel value into one image.

How did you store them?

What is the connection between the question and the tags "coder" and "compiler"?

Just use indexing to assign them, or else stitch them together:

wideImage1 = [image1, image2, image3, ..... image32];
tallImage = [wideImage1; wideImage2, ..... wideImage32];

I don't know what form your individual images are stored in so I can't do more without guessing.

Can you please do the same by using loops ? I have more than 100000 blocks, so it is impossible to write like this. Thank you.

What form are your blocks stored in at the moment?

Please don't say you have a hundred thousand separately named variables!
