Yes…they are standard encoded.
I can upload 10 files, all from the same batch of photos from the same camera/source. 6 will upload just fine while the other 4 gets to error messages. I have tried manipulating them in a variety of ways in Photoshop, but nothing seems to work on these photos.
And I can’t find a good gallery plugin that doesn’t rely on the wp media gallery. So so far, I’m screwed on getting a gallery up and running…
