SC server Cannot generate thumbnail

[lauren@paradisepartners]

Hello,

We're using SuperContainer 2.899 with FileMaker Server 13 on Windows 7. Our Windows FileMaker 13.0 v9 Pro clients don't always see image thumbnails. This is whether the URL includes noapplet or not. The image thumbnails do appear if I add a height parameter to the URL (you'll see why I tried that in the log). Any idea why this is happening? Here's the log from the server:

Thanks,

Hi, Lauren

I'm not reproducing the issue, I want to make sure that this is still not a problem in the current version.  Could you provide me the exact URL that's failing for you.
