YAY! PNG AVATARS! And bigger too!
adnedarn, rules! he gets cookies, lots and lots of cookies! cookies for all the admins!
But I really do think He would like bigger posts! than just a few words! (just a thought)
You can obtion a ping file within file specs by:
in adobe photoshop when you're ready to save your picture. Select "save for web" on the right select "PNG-8" then save. (Just incase you didnt' know how... Saving it normally as a PNG file, or as the larger PNG file will be too big. This size allows for plenty of quality.
WHAT! you need photoshop to get your own avatar!!
Everything is explainable. The seemingly unexplainable is but a result of our insufficient knowledge.- Hans Brewer
no one said that...
He's just saying that for most people who make their avatars to PNG files, with photo shop, or any other program like it should make it smaller cause the KB's of the photo get to big.
but I think you can make PNG files smaller with paint as well.
What's going on, what's this?
Where am I?
what is the benefit of PNG avatars over jpegs?
nepenthes_ak's new avatar is nice and crisp and clear..looks great!
but its still 28K in size..pretty big for an image that small.
so what is the deal with PNGs supposed to be?

scottychaos- You're correct. It's too big! lol I told him to turn it down while we were chatting last night. But he had bed and school- I'm sure he'll get it turned down today. those 2 extra KBs are making me angry!!! I think the main benifit is clairity, but they do tend to have larger file sizes. That's why I gave how to turn that down using adobe. But you can also make animations with it... I think the main benifit is some online file storing sites use that format. So now you can link those to here.
Short for Portable Network Graphics, and pronounced ping, a new bit-mapped graphics format similar to GIF. In fact, PNG was approved as a standard by the World Wide Web consortium to replace GIF because GIF uses a patented data compression algorithm called LZW. In contrast, PNG is completely patent- and license-free. The most recent versions of Netscape Navigator and Microsoft Internet Explorer now support PNG.
Most computer graphics are stored as a set of pixels, or dots that represent the image. *Imagine drawing a grid over an image, and saying that each cell can only be one color. *Each pixel has a number stored with it, listing how much of each primary color is included which tells the computer what color that pixel is. *In effect, the computer can draw each of these pixels at the right color and give the illusion of a continuous image. *Obviously, the more pixels you have, and the more space you use for color information, the more quality there is but the more data you need to store.Originally Posted by [b
For instance, letís say you use a 100x100 pixel image for an avatar. *That's 10,000 pixels. *At 24 bits per pixel to store color information that comes to a minimum file size of (10,000 x 24) 240,000 bits, which can also be stated as 30,000 bytes or 30kb. *30k is pushing it when you will be loading as many as ten of these on every single forum post, and if you want to use something larger like a 150x200 pixel image your file size will increase by 200%! *So what we want to do is find a way to compress them; make them use less space while showing the same image
JPGs use what's called a 'lossy' compression, aptly named because it discards (or loses) some of the information in order to save file size. *This results in more abrupt gradients and artifacts around contrasting edges. *However, if the imperfections are small enough our eyes will glaze right over them. *Even in these cases, however, some detail is lost and the image tends to appear a little less clear and less vibrant. *This especially becomes a problem with smaller images such as avatars or signatures.
GIF files use what's called a 'lossless' compression, which means that no information is discarded at all. *Insisting on keeping all of your data means that the file will appear exactly like the original every time with smooth gradients, sharp edges, and no artifacts. *However, it also results in a much larger file size as nothing can be approximated. *To get around this GIF files are stored with only 8 bits per pixel of color information. *This allows a massive reduction in file size, but decreases the available colors for any given pixel from 16.7 million to 256. *Amazingly, most images still tend to look pretty good with this reduction in color depth, but photos tend to appear dithered and with sharp gradients.
PNG is similar to a GIF, but with two important differences. *As noted above the compression algorithm is different and, in addition to being more open, provides better compression resulting in slightly smaller files. *More importantly, PNGs allow you to save your files with 24 bits of color information per pixel if you wish. *This results in a larger file size, but provides the maximum possible image quality of any format. *This is a favorite of photographers and artists, as file size is secondary to image quality for us...er, I mean them.
The suggestion above is to save your file as a PNG-8, or a PNG file with 8 bits per pixel of color information. *I would recommend saving as a PNG-24 if you have a photographic avatar, or simply using a JPG. *The PNG-24 will provide maximum quality, but if it results in too large of a file a JPG would look infinitely better than a PNG-8 at the same file size (on most photographic images at least). *Your mileage may vary, of course, so do your own testing.
Wow- that's alot of information! Thanks for taking the time to write that.. Although the png-8 may have less quality.. I recomended it because I first saved an image at png-24 at the pixil size, and it was about 60k (I think) I resaved the same image as png-8 at the new pixil size, and the file was MUCH smaller... And I though the image still looked good. Here is my product, at 120x140 and only 17.91kb
