great work on the module, first off  ;D

Unfortunately thumbnails do not seem to work for me much like many others. I'm running opensolaris (Not shared, all mine :-) ), GD is enabled, perms seem to be correct, I checked the page  source and only two .js calls are made and they belong to this plugin. I'm using a freshly installed Joomla 1.0.13.

I started out with IMAGE.JPG, them renamed to image.jpg, then converted it to image.png. None of which would produce a thumbnail.

Here is some further info that hopefully will help. I've got a feeling that showthumb.php might need some work, not entirely sure. Hopefully someone here might be able to shed some light.

Thanks!

Sorry, if you want to see what things look like feel free:

edit/update:  I hadn't tried using .gif's at this point, so I thought I would try. Interesting enough the .gif worked?! Looked like hell, but it did work :-)

Now, how to make .jpg work  :-\

edit 2:

I've noticed that I get good results going to (I receive te thimb):
www.bsdboy.com/mambots/content/plugin_jw_sig/showthumb.php?img=hollistertrip/test.gif&width=200&height=200&quality=80

Bad results going to:
www.bsdboy.com/mambots/content/plugin_jw_sig/showthumb.php?img=hollistertrip/test.jpg&width=200&height=200&quality=80

Both files exist.

Partially/mostly resolved!

I managed to get jpg support, already had gif support but still don't have png support. I can live with this 8)

Apparently there is a problem linking the GD libraries when building php from source, you must specify --with-jpeg-dir BEFORE --with-gd. This did not seem to do the trick with png support.

./configure --with-apxs2=/usr/local/apache/bin/apxs --with-mysql=/usr/local/mysql --prefix=/usr/local/php --with-config-file-path=/usr/local/php --with-jpeg-dir --with-png-dir --with-zlib --with-gettext --with-gdbm --with-gd --enable-mbstring
