Hi
I purchased, downloaded and installed the 1.5 version.

first it just said invalid file type - the images are .jpg for goodness sake!

I ran the test.php as suggested - yes it had the ["GD Version"]=>  string(27) "bundled (2.0.28 compatible)"

The I found the bit about uppercase in the file name plugins/content/jwsigpro.php

Line 140 reads:
Code:
$images[] = trim(strtolower($f));
This should be changed to:
Code:
$images[] = trim($f);
Basically, just take the function that forces the filenames to lower case.

So I made this change and now I get

"Error creating Thumbnail" for every image.

So what could it be? Access to the temp folder? - I made it 644 as requested (it suggested 644 or 777)

Is there a list of hints about all lower case, which image types it supports?

No forum info on "Error Creating Thumbnail"

I have searched for a user manual? Is there one? I can't find it.

Ok (all those errors were at 1am)  Thismorning I chmod the temp file to 777 and now it works!

I'm new to Joomla and having trouble with getting the thumbnails to appear - I have pages created prior to my working on my site that work with the thumbnails, but no new galleries that I create will work.

I've read a lot about the permissions on the temp folder - where and how do I check these?

Yes my friend jay44!
Cause a bug of SIG Pro for the j!1.5, the strtolower function
create an "invalid file type" problem.

The solution is to rename the images in lowercase, or remove the strtolower from the script.

About the permissions of the folder, if the joomla doesn't read the folder
we need to change the permissions to 777 or 644.

Thank you!
