Mistake # 1: How often do you blog Blogger blogs that the blogspot upload uploads related to picasaweb.google.com or Google+ that appear? Then delete all picasaweb.google.com or Google+ and then back to Blog. Encountered “Image error due to deletion when unknown”. Since photos uploaded to Blogspotupload on Google+ are stored at picasaweb.google.com. The only solution is to upload all the deleted photos instead of linking each image
Error 2: Error by the network operator is sure to know everyone, the network only block domain contains .blogspot.com only! So where is the Blogger user exit?
Option 1: Manual editing: When uploading pictures, the image link is * .bp.blogspot.com, just move the article to HTML mode and then edit the link to lh4.googleusercontent.com or lh4.ggpht.com. OK.
