Generators are signs, images, graphics that let you add your own text too.

13 Fantastic and Fun Image Generators
From Mashable, Most of the tools on this list are web-based and as easy to use as filling in a web form. We’ve added a couple of desktop applications that make visual communication a lot quicker and easier, even for those of us without a ton of graphic design skills.
Giant Cookie
Type your message and it will be placed in a cookie. This could be used on an infographic on nutrition or chocolate.

This could be a fun way to present information - turn it into a newspaper headline.

Movie Clapper Board
Does your infographic relate to any movie? Or maybe the title of your infographic is the same title as a famous movie? Use the clapboard in place of the usual title.
Generators are all over the Internet.

Chocolate Candy Bar
Use this for a chocolate infographic or for the literature book, Charlie and the Chocolate Factory. Infographics for literature books could include an author profile, interesting quotes from the book, a synopsis of the book or a teaser, and a poll from students who have read the book. Students can mashup fiction with nonfiction in a literature infographic. For example, in Charlie and the Chocolate Factory, a fiction book, pull out the nonfiction elements. How is chocolate made? Does it grow on trees (I wish!)? Where did it originate? And on and on and on!

Chalkboard Message
This might complement an infographic on how schools have changed in the last century.

Plane Banner
An infographic on advertising or airplanes might be a good place for this banner.
This could be fun to use with any of the Gary Paulsen books that take place in snowy areas. Upload a snowy scene from Minnesota or from Alaska - ah, the Iditarod. An infographic on the Iditarod could be pretty fascinating, especially for our students here in the midwest!

Restaurant Sign
This would work on an infographic on nutrition or economy.
