The old Windows photo viewer (which I'm fan of it) doesn't always work on my computer (windows 10). It opens some files, but for some others it shows the following error.
Windows Photo Viewer can't display this picture because there might not be enough memory available on your computer. Close some programs that you aren't using or free some hard disk (if it's almost full), and then try again.
I open the same file with other programs and they do show them. And I don't have any memory issue. So there must be something else causing windows photo viewer not oppening them.
Therefore I'm looking for a replacement. Is there any free software on windows for viewing image files like jpg, png etc. and doesn't collect any data from you? I found a Korean good free image viewer software, reading its manual, it seems it collects some data from your usage.
