I've just released version 3.0 of STGThumb.
The features added are related to STG Picture Merge. Picture Merge is an old, simple program from 2002, with a single purpose – merging two picture with an user-selected transparency setting. Recently it has become popular, due to several blog reviews.
Some users do a lot of images at once and asked for an easier way. STGThumb is the perfect way for me to do that and already does most of what was necessary.
What was added was the Merge a Picture setting, and the corresponding options:
It also includes a new Tools menu, which allows merging a single picture quickly, in the same exact way as the stand-alone program.
I may add extra options if users are interested – please comment below if there is anything you'd like.
