The more photos the merrier and it’s so easy to separate the wheat from the chaff. I find that taking a half dozen pictures of interesting locations allows for plenty of opportunity to find a great waymark default photo with a couple extra angles for good measure. The key for me is to re-size.
The other element is that with an extra large hard drive, backed up every now and then you can save your photos for a rainy day when a new category is added, you’ve been there and have the required photos and that icon in the grid gets filled sooner rather than later….welcome to cross-posting.
