image with dimension 5000x5000

I'm getting this error "Thread 1: Fatal error: texture load failed: The operation couldn’t be completed. (GLKTextureLoaderErrorDomain error 8.)"

I tried looking for some fix and what I got is this "https://stackoverflow.com/questions/8611063/glktextureloader-fails-when-loading-a-certain-texture-the-first-time-but-succee" but it's not easy to understand.
