Mac vs PC Thumbnail (0)

OK I have had a an issue with the Gallery Remote on the mac. It will not upload images failing with the "Unable to create thumbnail (0)". It works if I create the thumbnails in Gallery Remote first (Preferences -> resize before upload). That works fine.

But if I uncheck that box I get the error.

Here is the kicker...

Using a PC (same account details) it uploads fine without issue.

My issue is that my client now says it takes too long to upload a picture to the site as it can take up to 30sec each image. They upload around 100 at a time.

Can you help? Weird that it works fine on the pc and not the mac.

I am using an older version of Gallery 1.4.1 (cant upgrade as i have too many customisations).

GR version is the latest on both PC and Mac.
