You can use Adobe Photoshop's batch and action process. Have a picture open, once it's open hit the record button for the new action. Start putting whatever text you would and whatever you need on the pic. After you're done you can save it, close it, and hit stop on the action pallette. From there go to file and there is a option near the bottom with batch, from there you can go ahead and choose the directory you want to use your action on. Hope this helps.
