Saving images locally

I show thumbnails on one of my directories and give the required accreditation back to the source.

I'm playing around with different generators though because thumbnails.org don't index enough of the web.

I have no problems getting the images and saving them but when I try to view them I get text crap and not the image. If I download the image using FTP the image is as expected.

You can see my effort so far at http://www.top100vbulletin.com/cron/getThumbs.php and I do a var_dump(gd_info()); at the bottom but everything seems to be in order.

The relevant part of my script is ...

function saveGif ($imgname, $id)
{
	$im = @imagecreatefromgif ($imgname); /* Attempt to open */
	if (!$im) 
	{ /* See if it failed */
		$im = @imagecreatefrompng($imgname);
		if (!$im)
		{
			$im = @imagecreatefromjpeg($imgname);
			if (!$im)
			{
				$im = imagecreatetruecolor (150, 30); /* Create a blank image */
				$bgc = imagecolorallocate ($im, 255, 255, 255);
				$tc = imagecolorallocate ($im, 0, 0, 0);
				imagefilledrectangle ($im, 0, 0, 150, 30, $bgc);
				/* Output an errmsg */
				imagestring ($im, 1, 5, 5, "Error loading $imgname", $tc);
			}
		}
	}
	
	imagegif($im, '../images/thumbs/t'.$id.'.gif');
	imagejpeg($im, '../images/thumbs/t'.$id.'.jpg');
	imagepng($im, '../images/thumbs/t'.$id.'.png');
}//saveGif

Can anyone see where I'm going wrong?

 

You setting the content type with the header() function? That might be all you are missing.

For example for a PNG:

header("Content-type: image/png");

PHP:

 

Thanks Shawn, however that would make sense if I was outputting the image - but I'm saving it to a file and then using standard html <img> to call the image back up again.

Header() will impact on the output of the actual script which is standard html.

 

Oops... that's what I get for skimming.

Try taking off the "@" from the imagecreate functions... maybe it's throwing an error or something that you are suppressing...

 

A 403 is a HTTP error code though. Makes me think that your http request to GET the image is failing and is being forbidden by the server you are getting it from. If that's the case your script is probably otherwise working fine. It's saving what it gets (an http 403 forbidden message instead of an actual image).

 

Blast, had the folder permissions wrong. Not quite sure how that worked given that the images were being written and read was on for all but 775 made all the difference!

I've just discovered ya-right through another thread and that site seems to deliver the best result.

It's interesting to see how a slow server impacts on the thumbnail production.

Dataman - sent you a PM. Would love to have you onboard in the directory.
