I have a wordpress blog that posts images to social and bookmarking sites all day long. I want to add a line of text to these images that also gets displayed on these social sites, but I don't want the same text on all the images (about 200 images per day). Is there a solution(plugin) that lets me create a couple of lines of spun text and then insert it at the bottom of every post, so every image has a different byline. And the text should also be different per category. I have no idea how to do this, so any help is appreciated! Thank a lot!
