RE: Generate thumbnails from MySql database

["Snijders, Mark" <Mark.Snijders@atosorigin.com>]

hi all,

cause a lot of people are asking for a thumbnail script:

some explenation:

this script makes 2 new pics of a uploaded pic, 1 thumbnail and 1 bigger
picture (but the bigger one will all be of the same size.. it's better....

you also see this: if ($site=="who-r-u"){

this is because the sript is used on 2 servers , you can also see it like
this:

if ($site=="who-r-u"){  > you have to use this part if you have GD 1
compiled with pph
}else{ > this if you have gd2 compiled on your pc  so pic the right one and
trow away the rest!!!  but with gd2 the pics will be a lot better.

on http://www.nederlandmobiel.nl you can see how it is used!!

please don't mail me all back what the functions are doing, but go to
www.php.net and look them up

hope it helps you
