Q. What to do about this error message when uploading images: http error uploading images to wordpress site.
A. In my case I was uploading a Pinterest pin that happened to be too long. I went into GIMP and reduced the length to 1900 pixels. The image size went down from 796 to 632 KB and the image uploaded.
A. Add wp-admin to the URL on any of your blog pages. Mouse over the WordPress logo. You will see either WordPress.org or WordPress.com.
