Previously, any photo you want to use for your profile photo must first be hosted on the web and then you must get the proper URL. Got a question from a blogger recently who gave the URLs for the photos which she said when entered into the relevant field in the EDIT PROFILE page, resulted in error message. I tested with a test Blogger account using the give photo URLs and did not encounter any error message and the editing saved OK, but when the blog is viewed on the web, there were no photo in the "About Me" (Profile) section.
But I noticed something new. Now you can upload a photo stored in your computer for your profile photo. This was not available before.
I am in a hurry to test this new option (upload from computer) and hope if you have tried that, let us know your experience by leaving a comment. Please.
