I tried several times to upload the S5 post, but it kept failing on media. I read some troubleshooting posts and some guy said the same thing was happening,  but his pictures were in the media library. Lo and behold, so were mine. Several copies, in fact. I could add the photo from the media library, but it looks huge even though I resized it to 500 px. I can add screen shots the usual way. It’s got to be something to do with the image sizes. I could upload full size images from my S3, so it must be the phone, not the server configuration. Hmmm. Anyway that S5 post was from early yesterday morning;  I got the S5 on Thursday at work.
