General Support: Fatal Error with Beta 3

Mike,

The underlying Thumbnail generation library is not too good with error handling...

I usually see this error under two circumstances
a.) The pictures are way too large and the script is running out of memory while trying to generate the thumbnail
b.) The pictures you uploaded are corrupted. This can happen pretty easily if an image only gets half uploaded or isn't uploaded properly.

Do you get this error when you upload a single image? While importing? Try re-uploading your pictures or do only a couple at a time... one corrupted image in your import can cause the script to explode like that ...

I get a similar error when trying to upload anything but GIFS. For some reason, GIFS work perfectly...I've tried jpgs as small as 4KB and get an error:

I just get a white page with this output. When I go to that album, the picture has been successfully uploaded...but the text above turns into the LINK instead of a thumbnail...see for yourself what I am referring to:

Hey guys,

Sorry everyone is having problems with phpThumb. Although I can't reproduce the error myself, by looking at the debug messages I think I have a hunch... I believe it has to do with phpThumb's built in security features.

There is a string in that debug message that reads "!$this->config_allow_src_above_docroot therefore setting "/home/armst8/public_html/gallery/images/test/testalbum/test.jpg" to null". If you keep following the trail of debug messages, you'll notice that the rest of the failures are due to the filename being null, so I believe this is the source of the problem.

If you look at line 136 in /lib/phpthumb/phpthumb.class.php you'll see some security related settings

var $config_allow_src_above_docroot = false;

What happens if you set this to true?

It doesn't work!Still the same problem
