image resize

Anon

How would I set an image width to equal less than 350 while maintaining its ratio, not matter what size it is.

Only set the width="" attribute of the image tag.

lol, i meant this;
let's say I have a table that has to be less than 350 px wide, a user is going to input an image that I have no control over it's size. To keep my page looking good, the image must be less than 350 px wide. Now I can do a width='350' in the image tag, that's no problem, but if the user puts a image that's 1024 x 768, the image is going to look horrible at 350 x 768. So, i need to reduce both the image width and height in ration to one another.
so that an image that's 700 x 500 will display on my site as 350 x 250. Now, I can the the image size, but how can I scale it down to fit in the page in proportion to the height, so that the image wont be distorted

gotcha... in that case check out the GetImageSize function.

array getimagesize (string filename [, array imageinfo])

I think it's exactly what you need.

if anybody wants an image resize script:

$imgurl="http://www.mypage.com/myimage.jpg";
$size = GetImageSize($imgurl);
$max=350;
$width=$size[0];
$height=$size[1];

if ($width > $max){
$one=$width / $max;
$wid=$width / $one;
$hei=$height / $one;

}
else {
$wid=$width;
$hei=$height;}
