As the saying goes, a picture is worth a thousand words–especially true in a SBIR/STTR proposal where page-limits restrict the space available to make your point. That doesn’t mean you randomly insert pictures. Quality pictures, graphics, and tables reinforce key points, help readers who process visually, and keep interest rather than long passages of text–you don’t want a bored reviewer!
Always read the solicitation to see the specific requirements and restrictions of an agency, but in general make sure:
• It is high quality and clear
• If it contains text, it is large enough to read
• It conveys your point, whether in color or printed in black & white
• It is referenced and explained in the text—it should be used to clarify a point made in the text
• It has an adequate caption and/or legend accompanying it
• You don’t use too many—graphics should enhance not replace text
• If you move text around, check that the numbering of the figures is still correct
