The Windows GUI is clean and powerful, and it will combine all (resized) pictures into one small ZIP file. Much more efficient than messing with pictures in the WordPress Web GUI such as with NextGen.
I did have to contact my hosting company to change the upload_max_filesize directive in php.ini, they did that in an online chat on the spot.
