Hub You - Image Formats and Web Design: JPG GIF PNG and SVG
Have you ever thought about what you do ... really?I don't mean have you really thought about it. I mean what do you really do?Many people look at their business card for a clue. I suggest you ask your clients.I know of one business coach who is seen as a marriage counselor. He helped one couple sort out their business goals and issues so well it's improved their marriage!Everyone sells products or services. The more successful people offer/sell what a client wants.That sounds so "Sales 101", doesn't it?But it's true.The key is t

PNG is a bitmap image format with lossless image compression and uses the .png or .PNG file extension. PNG was developed as a license-free replacement to GIF, albeit without animation support. MNG, PNG's cousin, was developed to succeed GIF animation feature. PNG has more advanced transparency options than GIF, allowing a full range of transparency as shown in the picture below. However, Internet Explorer 6 does not support native alpha-channel transparency, however, in Windows Internet Explorer 7 this is
ForumsForum advertising can be an effective form of driving traffic, although it does require some time – intensive work when you first get started with it.So what is a forum?A forum is an online interactive community where members can ask questions of each other, answer questions of each other, and provide help and resources to each other.The list building/traffic element stems from the idea that generally if someone is using a forum, or even reading posts in the forum actively, they are somewhat interested in the topic, more so perhaps than a casua
The JPEG image format was developed by the Joint Photographic Experts Group in the early 90s. JPEG images most often end with the file extension .jpg; although .jpeg, .JPEG, .JPG, .jpg, .jpe, .jfif, and .jfi are also used. JPEG is a lossy bitmap compression algorithm meant primarily for digital photos. Lossy means that when JPEG images are saved they are compressed to less than their original size, but this comes with a loss in quality. Generally when saving a JPEG, compression is defined in percentages, with 100% being the highest quality but biggest file size. As a rough guide, 95% to 85% is good for logos and images used in formatting. Images of people or landscapes can go down to as low as 65% without obviously noticeable artifacts on the image.
For web designers JPEGs save space and load time, and offer a good general image format for digital photos and some logos. When using JPEGs you must be careful to avoid image degradation. If a JPEG is edited and then saved again as a JPEG, your image will have deteriorated in quality because it has been compressed twice. Sometimes in only two or three generations this can render the image unusable. It is always best to save your images in a lossless format, such as .png, .tiff, .raw, or .xcf, and then, when needed, save the file as a JPEG. JPEGs are widely compatible on all modern browsers and are the most used image format on the web.
GIF
The GIF format, or Graphics Interchange Format, was introduced in 1987 by CompuServe and recognizable by the .gif file extension. It is a lossless bitmap compression format for color images and animation allowing the use of 256 colors out of a palette of 16 million. Lossless means that all of the information in the original image is saved in the saved GIF, although, because GIF only supports 256 colors it isn't truly a perfect reproduction to the viewer.
Today, GIF is used to display things like buttons and low/med-quality animation on websites. GIF is not recommended for use with photographs due to the 256 color limitation, although there are workarounds. GIF animated buttons and the like were once popular, now they are fading from use, particularly due to Flash and better taste. Notably, GIF supports transparency, allowing the use of on or off "see-through" effects with images. Currently, PNG and MNG are in the process of superseding the GIF image format.

I’m bored with keyword tools, so when Keyword Elite showed up I said: ‘Huh, more hype!’ After all, keyword research tools are ten a penny. And there are those services that will send you a bunch of keywords every month. Usually the keywords are about things you’re not interested in and can’t see how anyone else would be.Oh, yes, I’ve bought these things, and some are still sitting clogging up my hard drive – because they were no good.All dressed up in a fancy packageSo I looked at Keyword Elite with suspicion – I didn’t want to waste more money. And the blu

I think that anyone who is a work-at-home mother must run into this issue - how do you manage your work time while at home and also taking care of your children?Do you schedule a strict regimen and then stick to it no matter what? Hmmm. Well, if you're a mother you might have tried this and found out that's it's not quite possible while also handling the various interesting adventures that come up with children. OK, I'll just go ahead and say it - uh uh, it's not going to happen. :)You know, I don't know that there is an exact answer to this. Som

They are increasingly more important in our personal lives, in our work environments and in business circles.Just how important are they today?In most work places the employees name has become the main id attached to the company address i.e. colin.thomson@abccompany.co.uk for all correspondence, with the company domain name as the main part of that address.Business’s the world over, where they have managed to, are obtaining the Domain Names of their companies for obvious reasons. So important has

As of now PNG is less well supported than GIF by modern browsers.
For web designers PNG is useful for images with varied transparency and screenshots. However, PNG's often large file sizes preclude it from use as a digital photography format on the web. They may not show up correctly in some browsers.
SVG
SVG, or Scalable Vector Graphics, is one of the most interesting, and potentially useful image formats today. Unlike the other formats here, SVG is a XML mark-up language for vector graphics. Vector graphics, according to Wikipedia, is the use of geometrical primitives such as points, lines, curves, and polygons to represent images in computer graphics. Instead of having all of the information for each pixel in an image, as all of the prior image formats do, SVG defines things in these geometrical primitives. This means, when you increase the size of an SVG image, it always stays sharp, and never becomes pixilated. This can be quite useful for logos and other simple graphics, allowing for many different sizes of the same image to be used with no loss in quality. Also, SVG images typically have very small file sizes. As seen in the picture, SVG graphics are not photo-realistic. They also require different skills and, generally, different programs to create them.
As for web design, SVG files are the dream for quality of images; unfortunately, Internet Explorer 6 and Safari both require plug-ins to view SVG files. Still, SVG images can be used as a lossless image used as the archive version, then converted into JPEG or PNG files for use on the web.
