I've just released STGThumb 3.10 .
The biggest change in this release is the addition of a CSS based instant photo effect. I've added a new sample album with this effect on.
As you can see, the effect adds a white border and drop shadow that looks like a Polaroid photo. Personally I really like how it looks, and I think some of you will too.
There were also some minor fixes, and changes in the defaults for album – particularly, I changed the yellow background default (which I started really disliking over the years) to a light gray.
For next release, I'm planning to add support for custom fonts from Google's Webfonts.
