Images are not displayed and errors such as "cocos2d: CCTexture2D: use RGB565 texture because the image does not have alpha" are displayed

I am building an application using Box2D in which I get images from the asset library and display them as sprites.

here is the code i made:

Retrieving Images from the Resource Library:

CGImageRef imgRef = [[mutArrAssetPhotos objectAtIndex:i] thumbnail];

Creating Texture2D:

CCTexture2D *spriteTexture = [[CCTexture2D alloc]initWithCGImage:imgRef resolutionType:kCCResolutionUnknown];

Creating sprites from textures:

CCSprite *paddle = [CCSprite spriteWithTexture:spriteTexture];

This gives me a warning in the console, for example:

"cocos2d: CCTexture2D: Using RGB565 texture since image has no alpha"

It still works fine in the simulator, although it’s a warning, but the device’s images are not displayed.

But instead, if I used:

CCSprite *paddle = [CCSprite spriteWithFile:@"img.png"];

It works fine and gives no warning either.

Can anyone help? Thanks at Advance.
