You can upload a Profile Header Image directly from your profile page by clicking the 'Update image' button at the top right corner. For best results, upload JPG or PNG images of at least 2480 x 520 pixels with a 2MB size limit. Please avoid using text within your Header Image as it will be cropped on smaller screens.
Once you have selected an image to upload you have the option to drag the image up and down or to zoom in and out on the image. If you do not have the ability to zoom, then this is because your image is less than 1240 x 260 pixels.
If you want to replace or delete your current image, then you just need to click the “Update Image” button again. If you delete your image, the Profile Header Image will return to a gradient based upon the colors in your profile image.
