Why does it say my image is too low quality? 
Our system analyzes the size of your files to be sure that it can print well at poster size. Some files are simply too low resolution and enlarging them would result in a blurry, pixelated image. With some PDF files, it may even be a low resolution image that is in the overall layout of your poster and this will still flag it as low quality.
