Twitter announced today two updates to their mobile app and profile pages. Here is a little more information.
Twitter has introduced Header Images in the vein of Facebook Cover Images, accessable across all platforms. The header image is viewed on the Twitter profile page – the page the general public gets to when they are searching for your brand.
So far, no limitations on logos or calls to actions - great news for charities!
The introduction of header images also brings the avatar from the far left corner and places it center in the header image. Bios are also brought from the left corner to centered on the header image. The bottom of the image greys out automatically to highlight the text of the bio, which may impact decisions on what image to use.
To change the header image, go into the settings option, under design (https://twitter.com/settings/design) Under the Customize your Own section, it allows you to upload an image. The image space is about 520 x 260. Once selected, you can arrange the placement of the image. Be careful on the sizing, if the image is too wide for the space, Twitter may push the graphic to the background instead of into the header image.
The second update to Twitter is the ability to view photos on profiles on the mobile apps. In addition to the header images being visible on all apps, photo streams now appear below recent tweets.
