I would like to create a pdf as the image shows. In black regions, I have one or multiple images, while in red box region I have rotated text for describing rows in this region (In this picture I have three regions, in the last region I have one or two rows). It will be very nice I can draw a line for separating these regions.
Edit: I want captions on these pictures as well. Originally I've created the table with matlab, but I want to use LaTeX now: row labels turned 90 degrees in red, each row filled with small pictures, where each has a caption consisting of two numbers in blue, with lines separating the rows. And I also want to make use of the full page. It would be better if I could edit the horizontal padding between images and vertical alignment of these images.
