[Mediawiki-l] Images and thumbs in PHP safe mode

Mon Dec 20 00:11:07 UTC 2004

Apparently I was a bit too hasty. Got the image upload working and got a nice
formatting of them too on the pages. But the automated thumbs won't work. It
gives the following if I try to add a 'thumb' or - say a '180px' property to an
image :

Warning: shell_exec(): Cannot execute using backquotes in Safe Mode in
/customers/crewscut.com/crewscut.com/httpd.www/includes/Image.php on line 246

Warning: stat(): Stat failed for
/customers/crewscut.com/crewscut.com/httpd.www/images/thumb/8/80/180px-JJ_Sarup.jpg
(errno=2 - No such file or directory) in
/customers/crewscut.com/crewscut.com/httpd.www/includes/Image.php on line 313

Warning:
unlink(/customers/crewscut.com/crewscut.com/httpd.www/images/thumb/8/80/180px-JJ_Sarup.jpg):
No such file or directory in
/customers/crewscut.com/crewscut.com/httpd.www/includes/Image.php on line 316

Anyone knows what to do to make thumbs work also?
A search of the mail archives revealed no immediate result, although it is
apparent, that there are widespread problems with the PHP safe mode. (I run our
site on a external server, without a say in the configuration of PHP on the
server).

Kind regards,
Morten :-)
