Something that is increasingly becoming a real pain for me is the quality of everyday digital cameras. People are starting to take huge photos with their 10megapixel cameras and they have no idea how to resize their photos before uploading to my site.

I currently use imagecopyresampled to resize the photos on upload but it has it's limitations and the photos have to be under a certain dimension otherwise it is too much load on the server.

Is there any way that the user can upload a photo but use their own computers processing and ram to resize before sending the image to my server? I know php is serverside but surely there is some answer to this.

Or maybe there is a way of resizing on upload that keeps the quality good but doesn't take too much resource from the server?

Here are a couple of scripts that will allow you to resize the image on upload (server-side, not client-side):

I believe there are lots more on Hotscripts if you do a search for upload tools.

JpGraph is a good one too...

what is the best and server friendliest php function to just get the image file from a post and resize it?
I use imagecopyresampled but I know there are several other options such as imagecopyresize etc...

I think imagecopyresampled is your best bet to be honest

Cheers. At the moment my script resizes the image on upload to a reasonable size, then it creates a thumbnail also using imagecopyresampled. So the script has to:
upload image, create one 400x400 pixel image and one 50x50 pixel image.

Obviously, I don't need the thumbnail to be best quality like the larger one. What is the least labour intensive method of shrinking an image for a thumbnail. I don't want to resize it with html each time the page loads for obvious reasons.

Hey -- a response post by my friend here recently got blasted because maybe it was percieved as some kind of advertisement..... but seriously, it wasn't an ad, do check out FJcore's open source Silverlight project as a viable solution to client-side resize (whereas imagecopyresized is just a server-side solution.)
