popup image

[lawrie]

I can dynamically link a larger image to a thumbnail by the 'open browser
window' behaviour .... but the size of the pop up window has to be pre-set.
Is there anyway to link to the larger image and have the widow hug the
image?
I think one of the justso picture window extension does this but not with
php

Store the image dimensions in the database. Then base your popup size on the
wifth & height of the image.

Just looked at the code for 'open browser window & should be able to put the
dimensions in dynamically.

There's no need to do that with PHP. Use getimagesize() instead. It does
it all for you:

Using getimagesize is fine:
<?php
list($width, $height, $type, $attr) =
getimagesize("news_images/mr.green.jpg");
echo "<img src=\"news_images/mr.green.jpg\" $attr alt=\"getimagesize()
example\" />";
?>

However, I want to substitute dyanmic images and the following throws an
error:

<?php
list($width, $height, $type, $attr) =
getimagesize("news_images/$row_rs['image1_name']");
echo "<img src=\"news_images/$row_rs['image1_name']\" $attr
alt=\"getimagesize() example\" />";
?>


thanks for any help

It would help if you say what sort of error it produces. Just looking at
your code, though, it's probabaly because there's no space between the
variable names and the rest of the strings. Try this:

list($width, $height, $type, $attr) =
getimagesize("news_images/{$row_rs['image1_name']}");
echo "<img src=\"news_images/{$row_rs['image1_name']}\" $attr
alt=\"getimagesize() example\" />";

In other words, surround $row_rs['image1_name'] with curly braces so
that the PHP engine can parse it correctly as a variable.
