        plist =
        {
            CFBundleIconFiles = {
            “Icon.png”,
            “Icon@2x.png”,
            “Icon-Small-40.png”,
            “Icon-Small-40@2x.png”,
            “Icon-60.png”,

            “Icon-Small.png”,
            “Icon-Small@2x.png”
            },
        }
    },
    
    
}
 

in the config.lua I have

[lua]-- For iPads
if system.getInfo(“model”) == “iPad” or system.getInfo(“model”) == “iPad Simulator” then

application = {
content = {
graphicsCompatibility = 1,
width = 360,
height = 480,
scale = “zoomEven”,
audioPlayFrequency=“44100”,
fps = 60,
imageSuffix = {
["@2x"] = 2,
["@4x"] = 4,
}
}
}

– For “tall” sizes (iPhone 5 and new iTouch)
elseif display.pixelHeight > 960 then

application = {
content = {
graphicsCompatibility = 1,
width = 320,
height = 568,
scale = “zoomEven”,
audioPlayFrequency=“44100”,
fps = 60,
imageSuffix = {
["@2x"] = 2,
}
}
}

else – For traditional sizes (iPhone 4S & below, old iTouch)

application = {
content = {
graphicsCompatibility = 1,
width = 320,
height = 480,
scale = “zoomEven”,
audioPlayFrequency=“44100”,
fps = 60,
imageSuffix = {
["@2x"] = 2,
}
}
}

end
[/lua]

Is the Icon-76@2x.png file 152x152 and a 24bit PNG file?

Yes the Icon is 152x152 but, It is 32bit depth Png.

Just to make sure we are on the same page:

Red, Green, Blue 8 bit per channel + an Alpha  Channel (in Photoshop terms 24 bit, but if you add the extra 8 bits for the alpha channel it’s 32 bit).  <----needs to be this one.

vs. a Red, Green, Blue 32 bit per channel + an Alpha channel.  It needs to be the 8 bit per channel * 3 (or 4) color channels.  Not a 32 bit per channel * 3 (or 4) color channels.  As opposed to an 8bit Index ping where each bite is only 8 bits total.

The Icon is 152x152 and 32 bit depth png

This is the Icon for testing

http://s7.postimg.org/6j3fes5av/Icon_76_2x.png

Apple actually looks at all the .png files in there and looks for an image with the right sized icon for what it wants.  Is it possible you have another icon file in there that is 152x152?
