I first posted the pictures from Through the Looking Glass a few years ago, and promised to update them with better versions when I got the time.  So,I have done that (the post is HERE) and am also adding similar pictures from Alice in Wonderland.  For both books I am providing both very large scale JPG (or jpeg) versions, and smaller but still useful PNG images with transparent backgrounds.  This transparency is useful for many applications.  The jpg’s are available and easy to download in a number of sizes, up to a maximum of about 1800 pixels.  The PNG’s are available in one size only: 584 pixels on the longest side; you will need to resize them on your own.

The Wonderland Gallery is HERE.  The first item on the page is the subfolder with the PNG images.
