   After playing for a while in my game i get the next error:

   Image is Null
   cocos2d: Couldn't add image:imagename.png in CCTextureCache

   Texture names are fine since game already has the same texture loaded before and i'm sure image is not NULL.
   It only happens after playing for some time.

   What can be happening???

   Thank you.

   Actually the code is very long.
   Here's a bit.

   I initialize my Block like this in init:

   Block *block = [CCSprite spriteWithFile:file];
   block.scale = 0.74f;
   self.tag = 7;
   [GameManager sharedGameManager].emptyBlockCount--;
   [self addChild:block];
   return self;

   In Main Layer i do this:

   waitBlock = [Block node];
   waitBlock.position = ccp(273.0f, 437.0f);
   waitBlock.scale = 1.21f;
   waitBlock.rotation = 4;
   [self addChild:waitBlock];

   After 7-10 minutes of playing, console says cocos2d: Couldn't add image:imageFile.png in CCTextureCache
   although it is a valid reference to a texture.

   I tried using removeUnusedTextures, removeAllTextures and even purgeSharedTextureCache but nothing seems to work.
   Looks like a memory issue.
   Any ideas???

   I can't figure it out.
   I made a loading of all textures used in the game in CCtextureCache.
   And in the middle it just says couldn't add image, when it was added at loading.
   Can anyone help me here???
   Thank you

   I've started seeing the very same thing in my game. It doesn't happen in the simulator but happens every time on my device for the very same image. I've traced it to a failure in CCTextureCache:

   
// prevents overloading the autorelease pool
UIImage *image = [ [UIImage alloc] initWithContentsOfFile: fullpath ];
tex = [ [CCTexture2D alloc] initWithImage: image ];
[image release];

   if( tex )
   [textures setObject: tex forKey:path];
   else
   CCLOG(@"cocos2d: Couldn't add image:%@ in CCTextureCache", path);

   [tex release];


   I can't determine why it's failing. I've ruled out a memory issue because I get the same exception when I force the "bad" image to be cached first. I think it's something in the file, but don't know what. Anyone have any ideas?

   Have you tried changing:
   

   Block *block = [CCSprite spriteWithFile:file];

   to:
   

   Block *block = [Block spriteWithFile:file];

   This will work if Block is subclassed as a CCSprite

   Do an NSLog on file just before [CCSprite spriteWithFile] to see what file name gives the error. Perhaps you load a file that isn't added to your project?

   Also, if the errors are only happening in the device, it sounds like the case is wrong. the iDevice is case sensitive, while the mac (Simulator) is not. Make sure you have the names of you images in the correct case, eg:

   MyBlock.png vs myblock.png

   I don't know what agfa555's issue is, but I solved my problem by re-saving the image from Photoshop. I have no clue why the image was failing in the first place. It was included in the project AND the name was using the proper case. Without changing code, re-saving the image and re-deploying the app worked. Very frustrating.

    I have the same exact issue only it happens when I try to test my app on iPhone 3G with iOS 3.1.3
    When I run the same exact app on iOS 4 iphone 3GS it works just fine.

    this is the error log:

    Couldn't add image:Urban_Background.png in CCTextureCache
    2010-10-06 12:19:49.301 BLOWN[325:207] *** Assertion failure in -[GameScene addChild:z:], /Users/alexkreston/iPhone_Developmen_Projects/_repo/Whosh!!!/libs/cocos2d/CCNode.m:322
    2010-10-06 12:19:49.308 BLOWN[325:207] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Argument must be non-nil'

    The file is fine and works on iPhone iOS 4 device and simulator.

    please help!!!!!?????

    Another one possible cause for the error could be that image was not added to one of targets if there are several of them in a project.
    Ensure that 'Copy Bundle Resources' folder of a target contains image that cannot be loaded.

    I guest you edited the name of file. Example "image.jpg" to "image.png", this is illegal. The file name must be originally.

    I have found that when I rename files in XCode (for instance "Level1.tmx" to "level1.tmx") and build/run the project I get the same error as you. I think it might be because the file is actually not re-build on the iDevice because OS-X file system is not case sensitive but iOS is.

    Symptom is often that the game runs in the simulator but not on the iDevice.

    Try going to the Product menu and select "Clean" .. and then rebuild and run the game. Should work now.

    Hope it helps :) Caused me A LOT of frustrations!!!
