I read through your other forum and noted that some are requesting larger thumbnails. I don't need them, although settings for thumbnails would be nice. One other thing I noticed was that adding square or landscape photos causes the gallery to jump around.
Would it be possible to set a fixed size for the preview and have all generated previews cropped to fill? It seems that would stop the jumping.
It might also be nice to do with thumbnails themselves for a more consistent display.
Have I said this is a great plug-in yet? If not: Great plug-in. :-)
