SDL image

SDL_image is an image file loading library. It loads images as SDL surfaces and textures, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, TGA, TIFF, WEBP, XCF, XPM, XV

As of SDL_image 1.2.5, JPEG, PNG, TIFF, and WEBP image loading libraries are dynamically loaded, so if you don't need to load those formats, you don't need to include those shared libraries. libpng depends on libz, and libtiff depends on both libz and libjpeg.
