Most mature social networks do remove this information to prevent users accidentally sharing their locations. Can someone positively say whether Lemmy is aware enough to strip extra information from photos?

    Basically the PNG file format is a series of chunks. The most useful being the IDAT chunk which is the image data. IHDR has the info about the resolution too. Everything else can be removed and it should work the same as far as viewing is concerned. EXIF and TEXT are just two other chunks. I believe EXIF is for information about the camera. It seems useful for photographers. TEXT is just meant for any textual data you want to put into the image.

      How do you visualize and access all of this information within the image file?

        This is a python tool I was making recently to do this which is why it is all so fresh on my mind. There seem to be tools on webpages to do it too but I don’t know how well they work. Here is one. They are probably easier to get going.
