png resolution is wrong when opening file from the UV/Image Editor I was sent an png for a texture by a friend.
The image is 192 x 24 pixels

it's properties are correct in windows explorer when I view the downloaded file, but as soon as I open it in blender...it's y pixels are halved so it's very much blender. but I don't know why.

If I use the blender Image Editor and Alt+S to save the image again, the original is converted to 192 x 12 (Which is half the y)
You need to Uncheck the Fields checkbox
