You can easily display a picture, logo or other iconic avatar next to your name in your posts and comments in the Knowledge Base. There are two methods for doing this.
1) Associate your picture and your email address on Gravatar (be sure it's your work email address, the same one used here in our support system). Our site will pull your image from Gravatar with no further action on your part. If you change your image at Gravatar, it will change here, as well as all sites that use Gravatar to serve images.
2) Send your avatar image (picture or logo) to us as an attachment to a support ticket, and we'll add the image file to your support account. Changes or updates will be managed in the same way.
