[Plugin: NextGEN Gallery] Shadows Instead of Images

I’m stumped. I’m trying to get Next-Gen running on a fresh install of WP. Created a test gallery. Uploaded a photo. It uploaded ‘successfully’.

When I go to ‘Manage Gallery’ and edit the gallery, no thumbnail appears. When I click on ‘view’ the spiraling progress bar appears but never resolves.

I created a test WP page linking to the test gallery [gallery=1]. The test image is a shadow. It does not appear after clicking.

I’ve reset settings within Gallery and turned effects off. I’ve dropped the tables and done a fresh install.

If I go to ‘wp-content/gallery’ the test gallery exists with both the image and the thumbnail created. Both images are viewable within the directory via my control panel. Meaning, they can be viewed as perfect photos within the control panel.

Here’s my set-up:

WP – 2.5.1
NGG – .96 installed in /plugins/nggallery & enabled in WP
Platform – Debian
PHP Memory Limit – 64MB
PHP Upload Max Filesize – 50MB
PHP Post Max Size – 8MB

Appreciate any help anyone can give.
