Thumbnails not showing.

Then that’s why it’s not working. That’s too much information for your server to handle. The thumbnail creation is failing because your server is timing out. In this scenario, it’s best just to create your thumbnails yourself, with the appropriate prefix, and upload them to the same directory.

The prefix would be:
For small thumbs: _thumb_wd_ for wide thumbs, or _thumb_sq_ for square thumbs.
For large thumbs: _thumb_lrg_wd_ or _thumb_lrg_sq_
For medium thumbs: _thumb_med_wd_ or _thumb_med_sq_

Sizes for small: 60×40 or 40×40
Sizes for medium: 120×80 or 80×80
Sizes for large: 180×120 or 120×120

You can put some smaller images in a different directory and enable thumbnails on that to see how File Away creates them. Unfortunately, imagemagick isn’t designed for handling raw or super-hi-res images like that.

I’ll look into it, see what I can do.
Thanks so much.
