Invest in Professional Headshots
I work with a local Christian TV station called Keys Media. http://www.keysmedia.tv/
In my research for information on comp cards (or composition cards), which all actors need to provide to agencies, I came across this article from the Houston Chronicle. Notice that STEP 1 is to invest in professional headshots!! A professional photographer will be able to manage the lighting, posing, and editing of your images to make you look the best that you can be! And that's what you want to put forward.
This applies not only to actors but also to any professional. LinkedIn is a professional networking site and in my opinion, your headshot should be professional and not a cropped photo of you on vacation! You want potential employers to see that you take the job search seriously and professionally and that is what you will bring to your next job as well.
