Re: [PHP] =.jpg from another URL with PHP=

Thanks to all for your respones to my inquiry.

I placed the PHP script to open the .jpg from another URL in another file
and then inserted the HTML <IMG> tag to reference that file.   The result
was that it outputted a small sqaure with a red x  - but no image of the
map.


Any advice would be greatly appreciated.

  alert("The water temperature is " + product + " degrees fahrenheit");
  document.the_form.field_one.value=""
  document.the_form.field_one.focus()
 }

Make another file that has your code in it and sends an image/jpeg
