I know you are busy but I'm still wondering if you had time to code a bit on SER too. I would like to upload posts to my self hosted wordpress blogs and I would really like SER to upload the images with the article and not hotlinking them. Seeing the same images as wordpress featured image would be a huge boon but I don't know if that's even possible.
I guess some other popular CMS would benefit from this feature like Joomla and drupal too or anyone that is used for a PBN.
What do you think?
