How To Work The Imagery For A Site

We continue to see what file formats to use for each particular case, and their comparative advantages. The jpeg files so called, again, as a product of the first spell. Its popularity began with the era of digital photography, digital cameras as all-or most of them, record their photos with this format. The key feature of this format is that while quality is lost, for example, going from one format to jpeg, bmp, it can be administered graduating the level of file compression, which made it highly versatile. Jpeg images are based on the color system RGB (red, green, blue ie red, green and blue), so the images make their variation of color in varying degrees of these three components.

For this reason, and the excessive quality loss that comes when the image is enlarged, not recommended for work printed texts. So where do graphic designers design forms, do not use this format. But images of sites, is a format more than adequate, since visual quality is achieved with little relative weight. Finally, the PNG format () is the newest development. It was designed by Adobe, and the basic program to work on these graphs is the Fireworks, but there are many others. The quality is very high, but often a bit heavier than a gif or jpeg.

However, it is becoming more and more popular because it supports transparency. That is, you can design a graphic in png format with a transparent background, and so, when placed on a colored background or plot, would no longer be limited to square or rectangular images. By admitting the transparencies, we can design irregular images, and then to place them on the site, the non-image file takes no color, ie transparent. PNG itself is also square or rectangular like the others, but “hides” because we can put anything you want, in any form, but without drawing spaces take the color of background. When we include a graphic on a website, we must not shrink the size to fit into our page layout while the design, ie, shrinking the place. It is best to reduce it with a good image editor (like Photoshop, or Fireworks) and give the size and resolution necessary before placing it on the page. By including images on a web page, we must place the tags properly, ie, to include image name, description and text (the little yellow placard that appears when you mouse over it). All these factors contribute to good indexing of the site, since they are textual elements that are read by the crawlers. Therefore, should put the image a name that includes any of the keywords the site, or at least a relevant name, avoiding names like “12335.jpeg”, and including something like “printer-deskjet-Epson-RX4500.
