Img4Web is a batch image processor that allows the user to generate thumbnail images out of source pictures. All you have to do is list source images by using a drop box or choosing File > Open. Then set thumbnail image dimensions and select an export format. After configuring HTML settings, making sure that all four title labels are green, the Export button will become accessible. So just click it away!
A demo/trial version is available.
