Image Editing For The Web
Featured Publication So, your Web Page is going great, but there's just one problem.   How do you get pictures in there?   Well, assuming you've got the pictures already in image file format, here's how to get them onto that Web Page.   Two file formats are the ones you need to be concerned about.   They are Graphics Interchange Format (GIF extension) and Joint Photographic Experts Group (JPG extension).   If your files are not in one of these two formats, then you need to convert them. Most image editing programs will have a way to convert the files between different formats, as well as perform a variety of other functions to adjust for example brightness and contrast, colour tint and depth.   You should find a program that can handle both JPG and GIF files, since JPG are best for photographs, and GIF are better for drawings and animation.   A program like Ulead Systems' Finishing Touch will do just fine as an image editor, but you also need a drawing program like CorelDRAW (version 3 is great) to do original artwork and embellishments.   In the case of CorelDRAW version 3, importing can be done using GIF or TIF formats, and exporting using GIF.   When exporting keep the image dimensions in pixels close to the actual image size that you will see on the screen (a VGA screen is 640 x 400 pixels, SVGA is 800 x 600, and XGA is 1024 x 768, but images for the Web are generally much smaller than this).   The number one thing to remember in editing pictures for the Web is to keep the files as small as possible, since otherwise they may prevent the modem from loading your page in a reasonable time.   Resampling can make them smaller.   Without experience, you will be helped by viewing the image actual size and not using anything larger than it will be shown on the Web. You may also want to try converting between GIF and JPG formats to find the most compact one for a given image as the file size comparison can be quite different in different cases. Economy aside, JPG produce the most accurate colour rendering.   Once they are the right size and you are ready to put your JPG's or GIF's on the Web Page, here are a few things to keep in mind: The aspect ratio (the ratio of height to width) of photos determines whether they look right or not.   The image editor program should provide image file information, giving you the actual image size in pixels.   Before you put the image on the Web, try putting it in the Web Page and view it with a browser by opening the file, then make any changes needed in contrast, saturation etc. in the image editor until it looks right.   You must click "Reload" in the browser to display a new version of the image, and in some cases you even have to close and reopen the browser.   When you're satisfied, upload it to the Web.
