For your Twitter profile you can customize its header and background to match your individuality, voice or company. You can use default background colors, photos and default header settings for your Twitter profile anyways, but if you want to customize Twitter background and header then there are plenty of options. You can upload Twitter background photo and Twitter header photo. You can select any of the images that are available in Twitter profile settings and design settings. What I want to share, is different. I will show you how to use photos from Instagram and use those as background or header for Twitter. You can create photo collage from selected photos from Instagram to do that. You do not have to have Instagram account to do so.
