Rik,

Thanks for responding. In this case the class name is what it is.
..pad1em{padding: 1em;}

Was just messing with some spacing and will rename if I add some pretty
decorations. Any suggestions for this class?

thx..ron

Well hell yeah, post away!

I was trying to do it myself as I see a lot of posts asking for free work. :)

At this point storage isn't an issue and it takes 20 seconds to
generate the thumbs and the resized images from iPhoto. As opposed to
if I had a 1600x1200 pic and uploaded I think that takes more storage
than a 800px pic and a 100px thumb. Let me see if I can write a script
to calculate the storage difference... :)

So when I take pics I make a dir and make images and thumbs dir inside
of that. The I have a very simple php page with includes for header and
footer. Change the title, add my paragraph or two and then my thumbs
output. I tried to use iWeb for plain export of html pages but ends up
being more work because every file extension needs to be changed to
php, footer and header added, css line to be added. UGH.

So in 67 lines of code or less, read my images, display as thumbs
linking back to the originals, sorted by filename...

:)

Thanks,
Ron

ok...call this script get.thumb.nail.php (or whatever you'd like).
site.cfg.php is a configuration script that objectifies different things for
my site...in this case, where included directories are. hard-code as you see
fit. below this main script you'll find the functions used and supplied by
functions.inc.php. finally, below that, you'll see an example use of
everything together. if you have questions or need help, just post back.

cheers...
