Batch Image Manager is a small and free batch picture converter and resizer (or photo resizer). It can rename, resize and change the format of your images, photos and pictures.
It appears that the internals of this project are very well done. I get the overwhelming feeling that the guy (or gal) who created this program is a very competent person. The user interface, though, is mediocre. There is no user documentation, readme file, or instruction on how to the program. This is not a shortcoming if you are a programmer yourself because you will figure everything out quite quickly. There are no ToolTips on the controls to clarify things for an inexperienced user. It is rare that I see a project where I want to download the source code and polish it, This is one of those projects. The author has done almost everything perfectly. Just a few more hours in visual studio with this program could program could make it world class - the best of the best.
