Not opening png images

[MalcolmReed-ent]

System Information:

OS: Debian GNU/Linux Trixie (trixie/sid) x86_64
Kernel: Linux 6.10.3-amd64
Version: swayimg version 3.0

Issue Description: I am experiencing an issue with launching PNG images using swayimg. When I attempt to open an image file through a GUI file manager with the swayimg.desktop file, all image types open correctly except for PNG files. Additionally, when I try to view a PNG image from the terminal, the application hangs indefinitely, until i Ctrl+c it.

Could you please attach a sample PNG?

This is one of the images I was trying to open, but just wouldnt work.

Debian Trixie has swayimg 2.5. Did you compile swayimg yourself?

[MalcolmReed-ent]

Im on Debian Sid, im using

swayimg/unstable,now 3.0-1 amd64 [installed]
image viewer for Sway/Wayland

Looks like something wrong with libpng. I cant reproduce the bug in my system.
Could you build swayimg from source to check?

meson setup _build_dir
meson compile -C _build_dir
_build_dir/swayimg test.png

When i compiled the git version and running the distro's version, I noticed that PNGs work correctly on certain type of pngs. However, when using swayimg with both the compiled and repository versions on this image file 'swayimg/extra/icon_128.png', it works fine, but not for other PNG images. Down below is where i 'exiftool' both images, the first being the working one.

I am not sure, but may be github converted the image from #176 (comment)
Could you archive couple of problem images and attache the archive?

[artemsen]

I have installed Debian trixie/sid in QEMU VM.
Swayimg works as expected, at least this image opens fine.
So either github is converting the attachment or there is some problem on your local machine.
