You didn't include the #help in here ;)
See the help-channel on the chat, those who know more about the technical details of Steemit are there, but not 24/7 but you can check later for replies:

The error you've got isn't something common, or at least I haven't seen it before.
If you want a cheat solution, switch from Steemit to Steempeak.com, it's a different UI and the images are uploaded to steempeak servers instead of Steemit ones. Their website seems to be more stable.
Both work on the Steem blockchain, so same accounts & same content is visible and your post is seen on both sites.
Thanks for the info. I did have #help in there, but deleted it because 'error' was the main posting word in the hashtags that steemit recognized. dur ta dur. So I will edit again. I really appreciate all that you shared and will give these things a look. I'm on the backscratcher curation trail right now so just getting started and learning how each thing i do affects the other.
