PNGs created by tool cannot be opened again

[hugofant]

when embedding a text into image "b" and then embedding image "b" into image "a" there's following problem: image "b" can be extracted without any problem. image "b" will be saved as "PNG". but then image "b" can't be open again via "upload" freezes with "loading b..."

a bit strange: as workaround it can be renamed to "JPG", then it opens again and the text can also be extracted.....

Hey, Thanks for raising the issue. I recently started work on an entire-site rewrite, so this should be fixed as part of that 😄 ETA will be around 3-4 months.
