[Plugin: NextGEN Gallery] EXIF data doesnt show, how to use effects, resizing…

Hi, I have a few questions – am using the latest NextGEN and WP 2.6.

1. I found that the resizing feature doesnt quite seem to work? If I upload a large image, it is not resizing it. My resize options are 900×700, 85%, sample 4
2. EXIF is definitely not showing – am using the Tarski theme. I don’t see any EXIF data. My gallery options are set to resize images at 900×700. Some of my photos have been resized in Photoshop prior to uploading to NG
3. Can you explain further the effect options? I am using the thickbox effect and that works (the thumbnail pops up the image in what looks like a lightbox). But if I select any of the other options, I don’t see any effect? Can you explain how to choose the other options? There is also a lightbox option – but isn’t thickbox doing the same thing..??
