What is a good source to find royalty free HDRi to practice with ? It seems the ones i keep seeing claim to be hdri but are jpeg. Should they be IMAGE.HDR ?
Zbyg on DeviantArt has created three HDRi-packages that are free to use at least for personal work:

You might be allowed to use them for other types of work as well but I can't remember how it was.
