How to resize images automatically

Hello,

I have a dating site. When members upload their images, how do I resize the images to be 300px width and let the height automatically?

some images are large so they load too slow.

Can you please help?

Thanks,

Jenny.

p.s.

Here is the upload image code block:
<input name = "image_<? echo $i;?>" type = "text" id="image_<? echo $i;?>" value="<? echo $image[$i];?>" size="20" readOnly >
<input type=BUTTON name=btn_name<? echo $i;?> value="Upload" onClick=attachment('image_<? echo $i;?>')>

Look into the GD library, specifically imagecopyresampled() (http://us2.php.net/manual/en/function.imagecopyresampled.php).

Thank you, I'll try that.

Try this..

Thanks.

did it work?

I tried to create a file called "resizeimg.php" and put your code in.
Then, I put this:
<?PHP
$dimensions_of_thumb=get_dims('http://domain/imagefolder/,200px);
$x_dimension=$dimensions_of_thumb[0];
$y_dimension=$dimensions_of_thumb[1];
?>

on the top of the file that member upload images when they register, but nothing happened. I only change to imagefolder/ because I want to resize all images in that folder, but it does not execute.

I placed on the top of this page:
<input name = "image_<? echo $i;?>" type = "text" id="image_<? echo $i;?>" value="<? echo $image[$i];?>" size="20" readOnly >
<input type=BUTTON name=btn_name<? echo $i;?> value="Upload" onClick=attachment('image_<? echo $i;?>')

Please advice.
Thanks.

Sorry for the late response.

I'm a bit confused as to exactly what you have done. Any chance I can see all the code?
