I just use Poser to make my thumbs, importing the finished image, postwork and sig all taken care of, as a background. I let it be full sized, bring it down to 845x610, or something like that, and save it as a jpeg at 95% for the full image for posting. Then I pull in a pre-made thumbnail, made in Poser the first time I used it, allow the image size to change according to the smaller image, then ask for an import of another image. I call in the new one, but when it wants to change the size to fit, I say "No." My new image now appears at the smaller size. I then save that as a jpeg at 85%, to keep the overall size down for posting. I always differentiate my images by using a "2" at the end of the title for the larger one and a "tn" at the end of the thumbs, so they will not be confused in moving them around. The only problem will be a slight border on some images, which doesn't bother me. I could crop them out, but don't bother taking the time. Because I have things set up how I want them, this process is quick and painless for me. Once I finish an image, it takes about two minutes to get both images for posting, which I promptly take to the galleries for the pleasure of all mankind (just in case all mankind might decide to visit our galleries as a means to escape the realities of the real world).
