No the error IS as follows

Warning: getimagesize(images/image.jpg) [function.getimagesize]: failed to open stream: No such file or directory in /home/townsfin/public_html/bizwebpage2.php on line 50

 

Warning: Division by zero in /home/townsfin/public_html/bizwebpage2.php on line 54

 

SO, your the image

$image = "images/image.jpg";

doesn't exist.. thus no sizes are pulled from

$size = getimagesize($image);

read the error again.. you know it makes sense

what about this

if i did it correctly it should shrink the image to fit in a box of 250x250 (proportianal)

 

<?php
$image = "images/image.jpg";
$size = getimagesize($image);
$NewHW = 250;
if($size[0] > $size[1])
{
$height =$NewHW ;
$width = ((100/$size[0]) * $NewHW );
}else{
$width =$NewHW ;
$height = ((100/$size[1]) * $NewHW );
}
?>

 

just incase the height is too big and the width is ok

your setting both height and width the same

 

try this

 

<?php
$image = "/business_images/stuufloadtsd.jpg";
$size = getimagesize($image);
$NewHW = 250;
if($size[0] > $size[1])
{
$height =$NewHW ;
$width = ((100/$size[0]) * $NewHW );
}else{
$width =$NewHW ;
$height = ((100/$size[1]) * $NewHW );
}

echo "<img src='$image' width='$width' height='$height'>"
?>

 

or post  the code that set the image up (aka the part that prints <img scr= ......)

this is the new changes i made to the codes in order to be congruent to my codes



$image2 = "$Picture2";
$size = getimagesize($image2);
$NewHW2 = 250;
if($size[0] > $size[1])
{
$height2 =$NewHW2 ;
$width2 = ((100/$size[0]) * $NewHW2 );
}else{
$width2 =$NewHW2 ;
$height2 = ((100/$size[1]) * $NewHW2 );
}

 

 

code that display

$image2 = preg_replace('#^.*/public_html#', '', $row['Picture2']);
           echo "<img src='$image2' width='$width2' height='$height2'>";

This will resize the image to the desired width while keeping the scale proportional:

 

<?php
$image = "images/image.jpg";
$size = getimagesize($image);

$scale = $size[0]/$size[1]; // width/height
$width = 250;
$height = $width * $scale;
?>
