You actually managed to get Steempeak to work..?
It used to work fine, but the last couple of posts I made through Steempeak looked perfectly fine on Steempeak, but when looking at it on SteemIt, the images didn't show, insetad, the markdown code was shown..
I hope they fixed the issue...
Try going to your settings and click on the API. Then choose a different one. It worked for me. Hopefully it just needed a little "kick".
Thanks for the tip
