Setting img src

[ljschrenk]

Hey All,

I have been reading through how I can assign an HTML file's img src tag by calling a PHP tag and have a few questions. Our version of Unix Sco won't let us install the GD library so I'm wondering if I won't be able to do this. But here's what I have thus far.

An HTML page that just has:

<img src="file.php?num=12345">

Then a PHP page that has the following:

$img = "http://www.url.com?MAP_SIZE=1500";
header("Content-type: application/x-www-urlform-encoded");
header("Content-length: " . filesize($img));
passthru($img);

Thanks for any help. 😃

Correct me if I'm wrong, but you're outputting an image, correct?

header("Content-type: application/x-www-urlform-encoded");

Did you read what that says? A 'form' is not an image.. at all....

Not only that, but you can't simply assign an URL to a variable. Read up about opening a file (or URL) through [man]fopen[/man] and using [man]fpassthru[/man], NOT [man]passthru[/man].

Also, you could get the appropriate content type using [man]mime_content_type[/man] instead of hard-coding a specific image type (only if you're retrieving an image, not a '?MAP_SIZE' etc.)

GD library is in no way required to open file streams and output their data, regardless if they are images or not.
