Image won't open

[StandingTNT]

It's been over a year since I worked on this image, so I don't really remember the details. I made the image from scratch and worked on it, then I saved it. Since then I'm not able to open it. In the file properties it says that it's .png, but i remember having layers and saving it as .pnd. No program is able to open it.

At this point I've given up, but thought that asking for help here is a good idea.

 

Exception:

Have you tried renaming it to have a .pdn extension

If you install this plugin, What's It - it will tell you the type of file you saved the image as.

 

If it is saved as a PNG then the layer structure is gone. PNG doesn't support layers.

 

If you saved it as a PDN (and it is masquerading as a PNG with an incorrect extension) then the layers should be preserved.
