Ok, someone gave me the above code to create a thumb. I want to know what varible I would use to echo the path to the image created in the function. Can anyone help me?

Easy thing .....
just correct the code here at the 2nd line in the function
->> getimagesize($fname);
getimagesize returns an array that is used in the rest of the function
correct ->> $size = getimagesize($fname);
it's just a mistyping error.
the output file is the 2nd argument
for ex should be used as follow:
resize("/mypath/image1.jpg","/mypath/thumbs/image1-thumb.jpg", 80,80,100);
I suggest to add some code for the proportions if you intend to have a nice looking thumb
