Images to Scan Sites

Big picture

Images are usually the reason for slow loading websites so that the image size, number of colors and the file format are important considerations when scanning and prepare your images.

The key points are:

1. What image will be used?

2. What is the image size to be?

3. How many colors to display the picture?

4. What is the best image format? (JPG, PNG, GIF)

5. How many photos you want to scan?

What image will be used?

Once the scanned image will be used for a website, then we not need an image resolution of 72 DPI.

A computer monitor is usually 72-75 points (DPI) output inches. If you use a larger picture called 300 DPI, the computer will have to process all the data, but the quality of the image displayed on the screen will be the same if 300 DPI and 72 DPI. You should not use more than 72 DPI for images on your site.

What is the size that the image be?

For example, if the site needs a 100 pixel by 100 pixel image, the image you create should be 100 by 100 pixels. You must specify the height of the real image and the width of an image in an HTML document, but not to use these tags to change the image display size. If you use a WYSIWYG editor and resize the image using the control handles (by dragging the corner of the image to make it smaller), the actual file size (MB) is the same and now browser must do some calculations together with processing of all image data and will most often blurred air.

How many colors to display the picture?

The number of colors in an image will also determine how fast the image is loaded. Most photos will use the 16 million colors that the JPG format supports. If your image is 256 colors or less, you can use the GIF format to reduce file size and load faster. You can use your image editing software (eg Photoshop) to change the number of colors and compare the differences.
What is the best image format (JPG, PNG, GIF)?

GIF (Graphics Interchange Format) - supports 256 colors and is best for images with only a few distinct colors, such as drawings, black and white images and most of the logos. 3. PNG (Portable Network Graphics) - Better compression than GIF. Some falls are that not all older browsers support the PNG format. PNG does not support animation.

You can take your images to an outside company that will analyze and put on a CD for you, but the costs can be as high as $ 0.40 per image (1000 X.40 = $ 400), depending on the resolution and size the original image cooler if you use an online service. You can do a Google search for "photo scanning service" to find a local service or online and check current prices.

You scan 1,000 images of the time? If you had the right scanner, you can reduce the amount of time for batch scanning in a large format scanner. This saves a lot of time you do not have to cut each individual image.


In short, the image size, number of colors and the file format are important considerations when scanning the web.
