- Pictures and images from scientific equipment should be sized according to the final dimensions of the poster when it prints out.
- You cannot make images larger - they will become pixellated and look unprofessional. Think of how pictures on balloons look when you blow them up. The same thing happens when you try to make a too-small image bigger in PowerPoint or Publisher.
- Pay attention to the resolution (dots per inch or dpi) of images.
- Most images from the web and screenshots from a computer are 72 dpi You can get nice printouts for images at 72 dpi, but they tend to be too small to fit on posters any larger than 8.5x11
- Printed images should ideally be no more than 200 dpi
- If you are exporting an image from scientific software, make sure to export at 200 dpi in .jpg, .png, .gif, or .tiff format.
