Hi,
I am a newbie here. I want to offer some help. But I am not a long-term user of image processing, so I only checked some free packages to help me with theThumbnail Creatingwork. But the one whose way of processing is simple and fast worked great for me. It is just one of many but I do like it because it is manual and easy to manipulate. Besides, thisImaging sitegives a lot of tutoials for processing different kinds of document and image formats. Share with you. You can also google someone for help. I hope you success. Good luck.
