Changing inline image widths programmatically.

[eluser]John_Betong[/eluser]
 
Just ran some more tests and this is version 002.

1. image $width is calculated.
2. div-box is drawn with a width of 470px
3. $width is passed to the <img > display code
4. text is displayed in the div-box and floats around the image if and only if the image width is < 470px
otherwise text will follow the image

Code:

<?php
        global $img;
        $img     = './images/please_lord.jpg';
        $dims    = getimagesize($img);
        // Debug stuff
        // echo '<pre>';
        //   print_r($dims);
        // echo '</pre>';
        // echo '$width = ' .$dims[0];
    ?&gt;
        
    
    <div style='width:640px; height:420px; margin:42px 0 0 42px; border:dotted 2px; background:#ffc; text-align:left; border:dotted'>
        <img src='&lt;?php echo $img ?&gt;' style='float:left; padding:1em; width:&lt;?php echo $dims[0] ?&gt;px; background:transparent' alt='fred' />
