All images must comply with Wikipedia's image use policy: in general, they must be free for reuse, including commercial use and use after alteration, though some "fair use" of non-free content is allowed in limited circumstances—see Wikipedia:Non-free content.
The resolution of 960H depends on whether the equipment is PAL or NTSC based: 960H represents 960 x 576 (PAL) or 960 x 480 (NTSC) pixels. [29] 960H represents an increase in pixels of some 30% over standard D1 resolution, which is 720 x 576 pixels (PAL), or 720 x 480 pixels (NTSC). The increased resolution over D1 comes as a result of a longer ...

Also, compressing PNGs may be useful, because PNG files ...
