Details - gdImagePng() puts the damaged image when no color was allocated:
<code>
#include <gd.h>
#include <stdio.h>

int main()
{
    gdImagePtr im;

    im = gdImageCreate(100, 100);
    gdImagePng(im, stdout);
    gdImageDestroy(im);
    return 0;
}
</code>
I think the error message of libpng but no output may be adequate.
