You could write yourself a little script to generate a thumbnail on the fly ... use an 
img tag like

<img src='thumbnailscript.php?image=thisimage.jpg'>

You could simply cycle through your array and let the thumbnail script create the 
image for you each time.

Have to say, not very efficient ... you'd be far better off either doing an upload 
form that creates your thumbnails at upload or writing a little PHP daemon that sits 
on the server and chucks back the image data when queried...

I would resize on upload...still automatic and only do it once rather than every page 
load...you'll bring your server to its knees if you have a large site with lots of 
hits (or even a small site with lots of hits).

BTW, everyone else, hallo !  Ronan here, I do php / mysql / gd / flash stuff to build 
db driven sites.  Also use templating and OOP with an in house content management 
system to provide generic back end administration sites for our clients.
