bucies image selector thingy

http://usenet.alt-html.org/image-selector-thingy.php

I hope brucie is around, but if not can anyone else help me understand his
php

$size [3]

the variable above is part of a long statement that joins variables and
strings together to form the usual image tag. The bit above is used to
insert the width and height of an image into its image tag. I don't know
what the number 3 is for inside the square brackets?

thanks (I can't remember how he made the php available, if it was
http://usenet.alt-html.org/image-selector-thingy.phps its not there now)

This is an array.

It may well be, but it doesn't mean Brucie will be asleep!

Thanks, I will enjoy reading up on the getimagesize() function tomorrow,
time for bed now. My first thoughts, without first reading up on this, is
that this function stores various bits of info about the image and the bit
about its width and height is in the 4th element of the array - just a
guess, probably wrong, can't see how two seperate bits of info (width and
height) could be stored in the same cell of the array anyway - thinking out
aloud here, in private, to half the world, oh dear, I'm rambling on - Good
night, or should it be good morning!

Bye
David

<q>Index 3 is a text string with the correct height="yyy" width="xxx"
string that can be used directly in an IMG tag. </q>
