One strange thing I have noticed. When dropping in pictures from my phone, android, every once in awhile I will forget to downsize first. You would think, no big deal just go back and resize, not.
For some reason it remembers my first attempt and no matter how much I reduce it first, even down to 20%, it will keep telling me the file is too big. My only recourse then, is to delete the copy I've typed in to go with the picture, get out of the page I was on, and restart my phone to clear everything out and start all over.
Not sure why I can't just go back and reduce the photo and insert it, but I can't. This has happened on my last two phones, both Samsung's, but different carriers.
