[9.060][OPEN] Only PNG files (extension .png) are allowed

hello ,

Management>>Customization>>Company logo

if i take a scrren shot from ubuntu that is bydefault to png and want to use as a company logo it give message " Only PNG files (extension .png) are allowed " even after uploading png file it say " Only PNG files (extension .png) are allowed "

problem is size here if you use default use or any size png it doesnt work but if you upload image of width of "195px and a height of 73px" same png image it works fine so there is problem "its wrong message" or we should mention image "must be size of 195*73"


edit: For best results the logo should have a width of 195px and a height of 73px as well as an transparent background.
thanks
