[RESOLVED] Image from Gallery2 ImageBlock

Javert03

Hey all, here's my problem:

I'm building a website that uses Gallery2 for a photo gallery, and I have a random image from the gallery show up in a boxout. I've used CSS to put a frame around the photo to make it look better. Thing is, the frame is an image of a fixed size, so the random photos from the gallery need to be 160X120 to fit in it. Most of the photos are 160X120, but a few are 120X160. Naturally then, when a 120X160 photo shows up, it gets squashed.

So here's what I wanted to do: Rather than excluding the 120X160 photos, I wanted to write some PHP that would read the dimensions of the photo being sent from the gallery, and change the CSS to use a different sized frame if the photo's width is less than its height. So I added this to the head.

<?php 
$image = readfile('http://localhost/gallery/main.php?g2_view=imageblock.External&g2_blocks=randomImage&g2_itemId=196&g2_show=none');
list($width, $height) = getimagesize($image);
if ($width < $height) {
	echo '<link rel="stylesheet" type="text/css" href="styles/img-mod.css" />';
	}
?>

And I added this in the boxout where I wanted the photo to appear:

<?php echo $image; ?>

Two things happen: First, the photo I want shows up at the very top of the page, and not in the boxout. Second, I get this error: "Warning: getimagesize(332) [function.getimagesize]: failed to open stream: No such file or directory in index.php on line 15." Why?

'http://localhost/gallery/main.php?g2_view=imageblock.External&g2_blocks=randomImage&g2_itemId=196&g2_show=none'

Use & in stead of & for a start.

Replacing & with &amp causes Gallery2 to mess up and only changes the number in the error I get to 592 as in "Warning: getimagesize(592)..."

I don't think that could be the problem because readfile() reads and displays the image perfectly. Before I started using getimagesize() to evaluate the photo, all I did to display it was this:

<?php @readfile('http://localhost/gallery/main.php?g2_view=imageblock.External&g2_blocks=randomImage&g2_itemId=196&g2_show=none'); ?>

Thanks for your help.

Could you post the entire script and a link? b/c it says the error is on line 15...

You should be able to view the page at http://example.gotdns.com. (at least for a while anyway). I attached index.php as index.txt, since it didn't like the .php. Thanks!

Try a completely new approach:

list($width, $height) = getimagesize("../gallery/$image");

Where $image is the filename of the image including the extension.

Now you ar echoing this: "http://localhost/gallery/main.php?g2_view=imageblock.External&g2_blocks=randomImage&g2_itemId=196&g2_show=none"

It is normal that the image won't show up.

When working with images i upload the file to a certain directory and store only the filename in a database, i get the filename from the database and hardcode the directory in my script. This approach is more logical and will give you less headache.

Thank you soo much for your help! Sorry I didn't post back sooner. I've been having a lot of trouble with my PHP installation (broken gd support) and my lack of PHP knowledge magnified the problem. :-P

So to make a very long story short, I decided to stick with using the imageBlock from Gallery2 instead of making a new database and hardcoding the images onto the page because G2 already has caching and thumbnails and everything else I don't have. :-D And instead of PHP I'm using Javascript to do my style alterations (about 10 lines, compared to who knows how many I'd need to make and populate a database, resize my images etc.). Someday when I figure out how to use G2's database, I'm gonna come back and do this in PHP, 'cause I prefer everything to be finished before the client sees it. Thanks again!
