Adding Graphics

When adding graphics to Pressbooks, consider the following:

• Images may need to be scaled down from large aspect ratios, especially with infographics. When exported to PDF, they are better quality, and readability improves.
• Make sure images are aligned (left, right or center). Otherwise, the captions appear in undesirable places in the PDF.
• Whenever an image needs to be significantly resized, check the file type and, if necessary, convert it to a PNG image. PNG is a lossless type, whereas JPG is compressed, therefore PNGs handle resizing better. Note that if the image is blurry to begin with, this will not fix the issue.
