libcurl downloads everything binary by default.

Something like this (untested code) might work:

int main(void)
{
  CURL *curl;
  CURLcode res;
  FILE *storehere;

  storehere=fopen("dumpit", "wb"); /* b for windows people */

  curl = curl_easy_init();
  if(curl) {
    curl_easy_setopt(curl, CURLOPT_URL, "http://imagesite.com/image.png");

    curl_easy_setopt(curl, CURLOPT_WRITEDATA, storehere); /* write here */

    /* If you use windows and libcurl as a DLL, you must also set a callback
       function with CURLOPT_WRITEFUNCTION */

    res = curl_easy_perform(curl);

    /* always cleanup */
    curl_easy_cleanup(curl);
  }
  return 0;
}
