Setting transparent images background in IrfanView

[wasyl]

Hi

I have some PNG images which consist of a black shape and a transparent background. Unfortunatelly, IrfanView shows transparent background as black color, so I see just black on black. I've found in Irfan settings that I can change the window's background color, but it changes only around the image, the transparent color is still black.

Is there any way to change the color displayed as transparent, or, optimally, use white-grey squares like photoshop?

Thanks in advance.

Reload the image after changing the window colour to white, or whatever.

Do also check the topmost option in the Viewing tab of the Options/Properties dialog.
Unless that is checked it will not be transparent. Instead you will see the color that was selected to be transparent from the original image. Again you need to reload the image after you have saved the changes before you see the new settings.
