    Please send the file with a bug report to Irfan Skiljan and let us know what he says. Tell him which program was used to create the file. See Help, About IrfanView for his address.

    I could open the file in IrfanView after saving it from Serif PhotoPlus X8.

    I have the same problem. Version 4.54 64 bit. I'm on Windows 10.

    I can open this image in any other program, i.e. Chrome or MS Paint. However Paint seems to handle it better than Chrome, which for some weird reason trims the image by around 70px in height.

    It's a screenshot generated by a game client (retrocores):

    I guess whoever developed the client made a shoddy work around decoding or image headers in screenshot capture, but then why this image opens on other programs? Can I make IrfanView be less strict about these faulty headers so it can open this image as well?

    This thread is about PNG files, but the image that you have attached is a JPG image. It opens just fine in IrfanView 4.54.

    I suggest attaching the original PNG image or BMP (or whatever it was).

    That's strange, it is a png, could it be that the uploader is converting it to jpg?

    It is the same problem as already reported and confirmed.
