How to make a multiplot figure from files


I would like to generate a composite figure in which I want to insert images saved in a folder. Suppose I have 12 images and want to show them in a single figure in which I have 4 rows and 3 columns. How can I achieve this task? How can I add the title to each subplot (it should correspond to the name of the file)?

Thank you in advance.


To be clear, are you using Matplotlib? Or else what do you mean about “figures” and “subplots”?

Yes, I think I have to use Matplotlib. I meant a composite figure in which each panel (subplot?) corresponds to an image (saved as .jpeg in a folder).


consider the following example as shown here:

Modify it for 4 rows by 3 columns. You should be able to extend it rather easily.
