all png or jpeg showing correctly on pc chrome browser, but not showing at all on mobile (iOS). I see only rectangle instead of image. But if i tap on image and make a save this image save correctly, the problem is only with image showing.
I found a problem, if remove srcset from image description, just for example
srcset="boombox.png 1x, email@example.com 2x
all works fine
Ohh its about pixel density, iPhone want x2 image and i need place it. Thabk you, question is closed.
