I take pictures of my littles in the area the cache was found. I usually place them away from GZ...especially if I know the cache is one that is meant to be harder. I keep a log book that is basically a geocaching journal and I also have a personal album that I post the pictures to. I do have a couple of pictures of just the cache containers...those were caches I found without my littles with me, but I never put the name of the cache itself in the information for those.
I also think you need to read the description of the cache. Some ask right in the description that you not post spoiler pictures (ie: the specific place the cache is hidden, the cache itself, etc.). When you are reading the description and even the logs for a cache, you can get the feel of what the CO had in mind....did they want the cache to be a really hard cache?...or is the primary purpose of the cache to get people to a place that means something to the CO and is just for fun??
