To upload a cover photo, first click on the 'Your Houzz' icon on the top left to load your professional profile.
Once on your profile page, hover the cursor over the current cover photo, and a 'Change your cover photo' button will appear on the right of your profile picture. Click the button and a pop up box will appear which will allow you to choose from the gallery of your existing project photos. Once you have chosen your photo click 'Use Photo', and a new screen will load which allows you to resize and reposition the image for best effect. When you are happy click 'Save'. This image will then be applied to your public profile.
Tip: Choose an image at least 1200px wide for best effect.
