As we continue to roll-out the new Twitter profile pages (https://blog.twitter.com/2014/coming-soon-a-whole-new-you-in-your-twitter-profile), we now have updated guidelines for image sizes that you upload via the REST API. We now recommend that profile banners be 1500x500 pixels in size, and that profile images (avatars) be 400x400 pixels in size. We've updated our documentation around this on the following pages.
User Profile Images and Banners
Profile Images (400x400):
POST account/update_profile_image
Profile Banners (1500x500):
GET users/profile_banner
POST account/update_profile_banner

The new profile is a mess in Opera 12:

can you do something to fix this?
Opera 12, or Opera 21?
I've just tried in Opera 21 (which appears to be the current / most recent version) and the layout looks good there.
Opera 12.17
All the other browsers work "like it should", I find the issue in the CSS, and I know that no body cares about the good Opera 12.17 so I apply to my browser the fix as it admit external CSS files to overrite the site ones.
On a business account I manage, I'm uploading a 1500 x 500 image that has a resolution of 600 dpi.
The font looks blurry because of my screen resolution is 1920 x 1080.
Wouldn't it be better to have a super large image that downsized, rather than a small image that is up-sized?
Uploaded a 1500x500 .png header, I get an internal server error on both chrome and ff.
I converter it to .jpg, it worked,but the quality is horrible.
Uploading a beautiful 1500x500 png file, the file gets blurry and faded. This is not ok. Solutions?
