Creating a slideshow with images and text overlays Does anyone know of a module or method to create a node where users can upload an image, add text on top of it through a WYSIWYG, then have the image combined with the text (merge the text and image into one jpg/png)?

We are trying to find a way for users in a school to add slides to our digital signage without using powerpoint, and I was wondering if there was a Drupal module that could do the job or help make it easier.
I don't believe that there's a module that supports the dynamic placing of text on top of an image in a wysiwyg editor. However, you should be able to use the imagecache_actions module to superimpose a text field onto an image field; IOW, you'd need to have separate fields (or a field collection) for the image and text. It also supports custom actions which should allow you to exploit the imageapi and GD as per your requirements.
