Like Kirsty said before, it is out of their control because of the amount of people viewing these forums and the age of the software being used. Raising the size of signatures will lower the load speed of the forums and use up space that is simply not there. Nothing is wrong with the current signature size.
Also raising the dimensions of signatures will only stretch the page out. Right now it is very easy to read everyone's posts without having this over sized image taking up the entire screen.
You make no sense and don't know what the hell your talking about, You guys are morons.. It's simple math people.. If a avatar is 500kb and a signature is 80kb per user... that's a total bandwidth of 580kb... way over what is intended to.. just look at the people avatars on the forums, right click and view image proprieties.. most users have around 200kb for a avatar.. It won't make the forums lower then they already are... not if you reverse it so the signatures are no limit and the avatars are ... it will be the same amount of speed. i should know i run servers and design websites for a living! and i wasn't talking about the image dimensions. Now if a avatar is 200kb and you guys don't care... why should a signature be limit a limit of at least 500kb. it won't even hurt the servers...
I think people equate bandwidth with speed by mistake. Speed means the amount of time it takes to cover a distance. That's really more like latency in networking terms. People have better bandwidth ("speed") because their connection can simply send/receive more data at once.
Just picture 2 pipes. One is 1 inch in diameter, and the other is 6 inches in diameter. Now imagine the volume of water that could flow through the 6 inch pipe versus the 1 inch pipe. The water itself flows at a similar rate through both pipes; the difference is that the wider pipe can handle more water. Replace "water" with "data" and you have a basic idea of what's going on.
When thinking about maximizing image quality, resolution is usually the first thing that comes to mind. However, resolution is not the only factor that impacts quality. The amount of bandwidth available and used can have a dramatic impact on image quality. In this report, we examine bandwidth and the effect that it has on quality across numerous cameras.
Which Image Quality is Better?
To better understand image quality, let's start by examining two samples of the same scene side by side:
Consider two questions:
Which camera has higher resolution? A or B?
Which camera is better? A or B?
It is pretty obvious that the image from Camera B is better so this should be a simple case.
The reality is that those images are from the same camera at the same resolution and frame rate (720p/30). All that was done to the camera was changing the Constant Bit Rate target from 512 Kb/s to 8 Mb/s.
Factors Impacting Quality
Even with the same resolution, two common settings impact quality:
Bit Rate: Most cameras can have their bit rate adjusted to specific levels (e.g., 512 Kb/s, 2 Mb/s, 8Mb/s, etc.)
Quantization Level: Most cameras can have the level of compression adjusted (often called a quality or compression setting with options from 1-10 or 0-100)
Typically, these are mutually exclusive. If you lock in bit rate, the camera will automatically adjust the quantization level to not exceed the bandwidth set. Vice versa, if you set the quantization level, the camera will automatically change the bandwidth consumed to make sure the quality / compression always stays at the same level.
Our Test Process
I wanted to better understand how changes in these two factors impact video quality. To do so, I did a series of tests with three HD cameras: the Axis P1344, the Sony CH140 and the Bosch NBN-921.
For the bandwidth tests, we tested each camera at the following levels:
I did this across a series of scenes to see how quality would vary in different conditions:
Daytime Indoors (300 lux)
Nighttime Indoors (.5 lux)
Finally, we did a similar series of tests varying the quality level of a VBR camera (the Axis across 0, 30, 60 and 100 levels) to better understand changes in quality and bandwidth consumption.
I just flawed your system.
