I don’t know about java codes and so forth, but I have like 30 images which I want to combine together (it’s one image divided) and making clickable some of them. I tried with html code, but the result is that everything is scattered and too big, unaligned. I’m getting crazy, please…
Have you tried using some html framework grid like bootstrap for example? Check it here: http://getbootstrap.com/
You also have a nice documentation on how to use it.
If you use the grid you can use the 1 column for each image, which will give you about 12 images per row, or you can divide it equally so you can manage those 30 images setup.
Best regards.
