Yes, they all load using LoadImage().
As I say, the exact same files work perfectly on my other computer which has a GF4 card. On that computer, Blitz seems happy to load any graphic in as a texture, regardless of size or shape (they're not powers of two). Unfortunately, I did all of my work on that computer, so wasn't aware of these limitations, so most of my textures are now obsolete.
