image file sizes

[gagz]

Hi-

I'm fairly new to PHP, having most of my background in perl and asp... I was wondering if there was a way on the fly to get the height/width of an image file so it could be resized to set width or height (depending on orientation), so I can keep it proportional...

Any thoughts?

Thanks...

If your installation of PHP has the GD library installed, then you can use the getimagesize() function (

so is the best way to create a thumbnail and a set size image to just get the image size, and set the h/w attributes of an img tag? or can I actually resize the image (not just make it look a different size)?

KarveR posted some code to resize an image and save the new image in a file. Want the best answers? Ask the best questions:
