Fundamentals Guide
In Column View, images are scaled to fit the width of the BlackBerrydevice screen, less 5 pixels for the scrollbar. If users want to
view the full image, they can click the Full Image menu item to download it. If the browser is communicating with the network
gateway, the network gateway sends the image to the browser without scaling it. However, network gateways typically have a
size limit for images.
Users can specify a limit for the number times that animations can loop. Animated GIFs can repeat either the default value of
10 times or the number of times specified in the GIF repeat value.
In BlackBerry® Device Software version 4.2.2 or later, users can specify the image quality for images rendered in the BlackBerry
Browser. The lower the image quality, the faster the image is rendered.
Progressive image rendering
In BlackBerry® Device Software version 4.2.2 or later, the BlackBerry® Browser renders images progressively. When the browser
retrieves a web page, a low quality version of each image displays quickly. After the entire web page is downloaded, the browser
retrieves the additional image file segments from the network gateway. The low quality images are enhanced as the additional
image file segments arrive, until they meet the image quality that is specified by the user.
Progressive image rendering is available with the following browser configurations and the associated network gateways:
•
The BlackBerry Browser configuration and the BlackBerry MDS Connection Service network gateway
•
The Internet Browser configuration and the BlackBerry Internet Service Browsing network gateway

Support for media streaming

In BlackBerry® Device Software version 4.3 or later, the BlackBerry® Browser supports streaming of audio and video files. The
BlackBerry Browser supports the following media types:
•
Video: WMV, h.263
•
Audio: MIDI, MP3, MP4, Wav
The browser supports media streaming over the HTTP or RTSP protocols.
When a user clicks a link to an audio or video file, the user can open the file, save it to the media card or device memory, or cancel
the download. If the user opens the file, the BlackBerry Browser opens the media application and the file begins streaming. When
the content is finished streaming, the user can close the media application to return to the browser. Streamed content is not
saved; users cannot replay media unless they download it again.
The network gateway might limit the size of the file that can be streamed. There are no size limitations if the content is streamed
over a Wi-Fi® connection.

Support for web feeds

In BlackBerry® Device Software version 4.2 or later, the BlackBerry® Browser supports the following web feed formats:
