If you've been serious about how your profile looks on Twitter, we will disappoint you. The social network deletes all images backgroundy and replaces them with a background in a neutral shade of blue.
In the Twitter Design settings, you will see that the image you were using is still there and clicking Save changes looks back.
Ωστόσο, όταν επισκέφτηκε το προφίλ σας από κάποιο άλλο πρόγραμμα περιήγησης που δεν είναι συνδεδεμένο στον account you will see that the image no longer exists.
No one knows why Twitter has decided to remove the profile customization feature.
Maybe because he wants to apply a uniform style, which is exactly what he does Facebook, where the background is the same for everyone.
