Two different places for HDRI's that I have ran across. From my search of this forum, they haven't been posted here before. (?)

First up is Joost Vanhoutte - http://joostvanhoutte.com/hdris

He has a pack of 26 free HDRI's (at the very top). All of them are 3,000 x 1,500 except for 3 of them, which are 12,000+ pixels wide. Just insert email address and they will send you a link. Worked fast when I did it.

NOTES;

• He has also included in the zip, the same .hdr's converted into .tbsky files, (which are just .hdr for use in the program Marmoset Toolbag 2). I just deleted these files, myself.

• Three of those are actually (very large) .exr files which do not exist as .hdr's so, I converted the .exr's to .hdr's with freeware program "Picturenaut"

• Picturenaut - http://www.hdrlabs.com/picturenaut/

Used here is his HDR called "TrainStation02.hdr"

Second site with free HDRI's

NoEmotion HDRs - http://noemotionhdrs.net/

These are some serious HDRI's! They are LARGE both in dimension and file size. So far, all the ones I have downloaded are 15,000 x 7,500 and weigh in at around 300Mb EACH. So, take care in choosing which ones you want before downloading. Did I mention there are 150 of them? They have them set up in categories and each file usually has 3 different download mirror links as bandwidth is usually being exceeded.

I'll mention that freeware program again, "Picturenaut", as I used this program to load the huge HDR's and resize copies down to 4k to 2k for faster loading during the tweaking stages - http://www.hdrlabs.com/picturenaut/

Used here with the HDR named "08-08_Sunset_A.hdr"

Wow, thank you very much for the links, AgentSmith! I use Reality 4.1.1 as my Poser rendering engine and am always looking for great HDRIs to use for lighting my scenes. I'll definitely be downloading some of these soon. Again, thank you! Anim8dtoon

No problem, you're welcome!

Thanks.
