The latest version of Preview app from OS X Mountain Lion onward feature a couple of fun menu items that let you quickly add comic book styled speech bubbles to any photo. It’s extremely easy to use, but it’s also easy to overlook, so here’s how to use them to add some humor to any picture:
Open an image in Preview and click the “Show Edit Toolbar” button that looks like a square with a pen in it, or hit Command+Shift+A
Click on either the speech bubble icon or the thought bubble icon, then click and drag on the picture to place the bubble
Type what you want in the bubble, adjusting the font and size as desired using the Fonts panel
Thought and speech bubbles can be moved around and resized just by clicking on them, but once they’re saved they’re stuck in place. You probably don’t want to save a goofy modification over the original photo (even though it’s easy to revert back now), so use Export or Save As to save the styled image instead.
Preview is a surprisingly great app and often underutilized, don’t miss a bunch of our other Preview tips to really appreciate the default Mac image viewer for all it can do.
