Ernst Haeckel's Kunstformen der Natur images with a Creative Commons image mask.
Jeff de Boer is an artist whose metal sculpture includes sets of armoured neckties, helmets for small animals such as dogs and cats, full body armour for rodents, and imaginary organic forms. Cool stuff.

The Beinecke Rare Book and Manuscript Library photo search page. This has large numbers of photos and other images, at fairly high resolution (typically 1400 pixels in the larger dimension). Finding stuff can be a bit hard as the keywording is very spotty. But there are "postcards" to Gertrude "Stein" and Alice "Toklas", photos from the construction of the Union Pacific "Railroad" (many of those are of interesting things along the way), Freud with his "dogs", etc. Every year I tried between 1840 and 1940 had at least one image.
