OpenCv, Insufficient memory error

I created this code in Opencv and after about 900 frames, this error appears:

OpenCV Error: Insufficient memory (Failed to allocate 921600 bytes) in function, file ..\..\..\..\ocv\opencv\src\cxcore\cxalloc.cpp, line 52

but I have initialized the variables once. Here is the code:

int _tmain(int argc, _TCHAR* argv[])
{
     IplImage * image;
     CvCapture * capture = cvCaptureFromCAM ( 0 );
     while ( 1 ){
         image = cvCreateImage ( cvSize ( 640,480 ) , 8, 3 );
         image = cvQueryFrame ( capture );
         cvShowImage ( "test", image );
         cvWaitKey ( 10 );
     }
}

You're constantly creating new images with cvCreateImage without using and, more importantly, without releasing them anywhere.

Just remove this line (it does not do anything other than eat up your memory):

image = cvCreateImage ( cvSize ( 640,480 ) , 8, 3 );

You would need to call cvReleaseImage at some point.
