If you are in any doubt as to why you absolutely must post a good, recognisable, smiling photo of yourself on your Profile page (and on Linked In, Twitter, your website, and your business card!) please read my blog post here.
HOW TO POST YOUR PHOTO
Log into the site and go to your My Page profile and hover the mouse over the photo (silhouette)
Click on Change Photo
You get to the My Settings page
Click Choose File next to the photo box
You get the Open File window on your computer
Navigate to the photo on your machine and click on it
Click Open, and the file path appears in the photo box (next to the Choose File button)
Then - and this is what I often forget to do - you go to the bottom of the page and click the blue Save button
Congratulations - you're done!
If you have any problems at all, please let me know and I'll be able to help... if nothing else works, create a temporary password (eg keith123) by going to Settings (below your Inbox, top right) then email the password to keith@networkinginsurrey and attach your photo so I can try posting it for you (this has always worked so far..!)
