Cut an image in irregular form

I solved the problem in another way.

I wrote, in html code in this logic (for my purpose) sequence:

Image 1)

Image 2)

Image 3)

Image 4)

Image 5)

The images are partialy one over another in the o previous order and

because of transparency I could not see that 3 was upon 2 and 5 was upon 4.

I need to click, for exemple, 2 and 4 without effect over 3 and 5

so the solution is to put the images in another order (in html language):

Image 1)

Image 3)

Image 5)

Image 2)

Image 4)

And this work perfecly.

Thank you again.

You can Mask an image to any shape you desire.

I don't understand what you mean by superimposed images.

On the web, all images are boxes.  All CSS divisions are boxes.

If you need transparency, place image on a transparent background layer denoted by the checkerboard pattern.

File > Export  > Export As PNG with transparency.   See screenshot.
