I did resolve the image [email protected]
not found issue while loading ipa to APP store using application loader.
The resolution is when you add the icons to Intel XDK, 180x180 icon should be lower case png for IOS. I did write like 180.PNG.
Intel XDK copies all other icons without the file extension and adds the png to the extension by itself. But for this 60x3 =180 size icon it copies the whole name.
While application loader performs asset check the icon with .PNG fails.
It took a tremendous amount of time for me to figure a silly issue. Good thing is that I understand the Intel XDK build log in a better way now.
