iTunes doesn't sync all the photos from computer folders
I have an iPhone 6 and I sync photo albums from my Windows computer using iTunes. iTunes lists the names of all the photo folders on my computer and when I select the folders I wish to sync, the number of photos in each folder is shown. However, some of these folders show the wrong number of photos. The size of the folder does not seem to matter. A 5,000 photo folder might show the correct number of photos, but a small folder might have a single photo missing. Or a folder could have the majority of the photos missing. All photos are JPEGs. Available space on my 64 GB iPhone is not an issue.
