Problem Uploading file

hello,
I tried to active the class and put it on my server.
Rights are on 777 and after the first error I saw that there is needed a folder called data, so i made it and made rights.
I get an error called:

Warning: imagecreatefromjpeg(data/bild0040.jpg): failed to open stream: No such file or directory in /srv/www/htdocs/web5/html/bilder/upload.inc.php on line 68
(and many errors after that)

after I tried to put an image up.
For testing i put the image manually up with FTP. Then when I try to put the same imagename up I get this error:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 19224 bytes) in /srv/www/htdocs/web5/html/bilder/upload.inc.php on line 68

So what could there be wrong ?
gdimage is active and functionable, is there any discription for installing the class ?

Thx for answers
Armin

First: check gd status
make file gdinfo.php
<?php
var_dump(gd_info());
?>
if not enabled from php.ini enable it or install package.
it depends by server configuration.

if you recompile "configure command" of php with this option:

'--with-freetype-dir=/usr' '--with-png-dir=/usr' '--with-xpm-dir=/usr' '--enable-gd-native-ttf' '--with-t1lib=/usr' '--without-gdbm' '--with-gettext' '--with-gmp' '--with-iconv' '--with-jpeg-dir=/usr'

you can skip Second point.

Second:
if you can't change server configuration use this, add one @ before image functions ... for example @ImageCreateFromPNG.

Third:
Set the correct directory to upload the file

Sorry for my bad english
