Vector and raster images are two different types of digital images that are used for different purposes.
Vector images are created using mathematical algorithms, and they are composed of points, lines, and shapes. Because they are created using mathematical equations, they can be scaled to any size without losing quality. This means that vector images are great for creating graphics that need to be resized, such as logos, illustrations, and diagrams. They are also suitable for line art and typography because they are composed of clean lines and shapes. Vector images are typically saved in file formats such as .eps, .ai, or .svg.
Raster images, on the other hand, are made up of a grid of pixels, and they are best suited for photographs or other images that contain a lot of detail. Because raster images are made up of pixels, they can become pixelated or lose quality when they are scaled. Raster images are typically saved in file formats such as .jpg, .png, or .bmp.
Which is Best for a Book?
For a book, vector images are generally considered to be the best choice.
Because books are printed and the images need to be resized to fit different pages, vector images will ensure that the illustrations and graphics maintain their quality when they are scaled.
Raster images can be used for photographs but it is important to have them in high resolution. Also, it’s worth noting that the final resolution and size of the images will depend on the printer and the type of paper used, so it’s important to check with the printer beforehand and make sure the images are of the correct resolution and size.

Didn’t know that.
Does an author need to know this, or is this a publishing item? Thanks for explaining the difference.
I suppose authors don’t “need” to know this, but if a publisher asks for an .svg file, you’ll know why.
If you have a graphic in your book, send the publisher an .eps, .ai or .svg file.
If you have a photograph in your book, send the publisher a .jpg, .png ore .bmp file.
