ImgThumb is a command line thumbnail creator software that generates smaller sized thumbnails and HTML for original pictures. Its inclusion of a GUI enables easy automation.

Not only that, but imgThumb can also generate a HTML file that's ready to be published on the internet, saving you time and effort.
When it comes to strengths, imgThumb has a few features that set it apart from other similar programs. Firstly, it's a command-line program, which means it can easily be embedded in a command-file (.bat or .cmd) to automate thumbnail creation. Along with this, there's a simple program (wimgThumb) included to start imgThumb.exe the normal Windows way.
Overall, imgThumb is versatile, allowing it to process a wide variety of picture formats such as BMP, JPEG, PCX, PGM, PICT, PNG, TGA, TIFF, and WMF. Lastly, the program enables you to create a HTML file that displays all of your thumbnails, which can be optionally linked to the original pictures.
The best part? imgThumb is free for personal use, so there's no need to spend any money to use the program's features.
