Just got the Digital Anarchy newsletter and this one popped out at me. The Cartoon Bubble plug-in is designed to create basic speech bubbles to go along with ToonIt Photo or any time you need to make your photos talk! It creates simple ellipse and rectangular speech bubbles that can be any size. You can adjust colors, fonts, outline thickness, and position. It's a great way to make your ToonIt images start speaking.
You don't need to be an owner of ToonIt, anyone can download it free and use it. It works on Windows and Mac and any recent version of Photoshop.
