Few days back I had posted about the WL Writer where people had some problem in posting to Blogger with images.
That problem has been fixed, as WL Writer Team Blog reports.
" The Picasa Data API newsgroup has reported they have fixed the issue that was causing posts that contain images to not publish on Blogger (thanks Jeff Fisher for the quick response!). We have verified that the fix does addresses the issue Writer was having publishing to Blogger."
If someone still faces the problem with Writer please post it on the Writer newsgroup.
