Almost the same to me. I can see some images in pdf but not all of them:
$ file * img1.png: PNG image, 26 x 25, 8-bit/color RGB, non-interlaced img2.png: PNG image, 24 x 24, 8-bit/color RGBA, non-interlaced img3.png: PNG image, 24 x 24, 8-bit/color RGBA, non-interlaced img4.png: PNG image, 833 x 945, 8-bit/color RGBA, non-interlaced img5.png: PNG image, 47 x 47, 8-bit colormap, non-interlaced img6.png: PNG image, 24 x 24, 8-bit/color RGBA, non-interlaced
Only img1.png and img5.png are shown in pdf but others are not.

Thanks for the info. It shows that this issue duplicates #12447.

Sorry. I did not noticed the initial author of this issue.
Pavel, can you please check if the images you are using are indeed PNG's with alpha channel and report your results here?

Tried pngs without alpha channel (got from here http://www.fnordware.com/superpng/samples.html) - the same result - no images in PDF export.

I tried note-8 URL Images.
The following error occurred.

Sorry, RFPDF (TCPDF) library is not supporting 16-bit depth PNG image.
