When I install SIG in Joomla 1.54 I get this error on installation.

Notice: Undefined variable: gd_support in /usr/local/pem/vhosts/123971/webspace/httpdocs/plugins/content/jwsig.php on line 83

And what happends is that in use the thumbnails are non images with cross over, but if I click them the fullsize images appear and seems ok.

What should I do to fix this row 83 problem?

Hello!

I've got the same problem. The plugin works, but on the top of a document with {gallery} tag, I got "Notice: Undefined variable: gd_support in ...\joomla\plugins\content\jwsig.php on line 83".

I've found reference to $gd_support variable in that line, but this variable isn't defined. In line 77 we initialize a $gdsupport variable so I changed variable name from line 83 to it.

To sum up, I've changed:to
Now, everything works fine. Is it a bug?

Best regards,
Marcin
