The Ktools PhotoStore software (www.ktools.net) automatically generates thumbnails, sample and large images with watermarks of the images in the database. If you change the settings regarding the image sizes only newly added images will get the new sizes.
The following simple script regenerates / resizes the thumbnails, sample and large images from the original images. It runs in batch mode, i.e it will work on every image you have in your stock_photos folder. It will overwrite your current i_, s_ and m_-versions of your images without warning. The sizes is set in the script (it does not read the current settings in the manager).
