Just recently I updated my Steemit.com profile picture. I was using https://imgsafe.org/ as recommended for Steemit users but the site is no longer online for whatever reasons.
Let me show you how to host your profile picture with a reliable well known service like Google Drive.
1. Make sure you have a Google Drive account and are logged in.
2. Upload your image file to Google Drive.
3. Right click on the file and click "Share".
4. Click "Advanced".
5. Click on "Change".
6. Change Link Sharing to "ON - Public on the web". Click "Save".
7. Copy the "Link to share" to your clipboard.
8. Head on over to http://gdurl.com/ and paste your share link. Click "Create Permalink".
9. A link will be generated for you called the "Standard URL". Copy this to your clipboard.
10. Head on over to your Steemit.com Profile Setting.
11. Paste the link into your "Profile Picture URL" and click "Update".
Your Steemit.com profile picture should now work smoothly without using other unreliable image hosting.
Please let me know what you think and leave any questions or comments below.
