Google Books API returns a JSON object that contains links to three or four different image sizes. Also, regarding CSS, browsers seem to scale the height down proportionally when you use CSS to modify the width. As a side note about Google Books, the cover images seem to only be available via HTTP, while organizational policy at many institutions requires HTTPS. This causes issues in newer browsers that don't allow HTTP content on an HTTPS site. Does anyone know of a workaround other than saving all the images server-side?

However, I would not recommend changing the ratio or increasing the size of the original image. With Retina displays (Apple), in order to keep any kind of non-pixelated cover art, you need an original graphic nearly twice the size you plan to display (depending on image quality), and then you could use CSS to scale it down correctly (that's one method and probably the easiest with the images coming from another source). Syndetics and Content Cafe both offer three sizes of covers, but I am unfamiliar with APIs that offer size options. GoodReads seems like it might, but I haven't tried it. In peace, Amy M.
