Photographs give life to a website and complete the message that the site wants to send to its readers. A website is not complete if it doesn’t contain images. Of course, the content is more important, a well balanced website has content plus corresponding images or pictures to attract visitors. One can include in his website digital photos depicting scenes or persons or maybe logos, illustrations, tables, diagrams, clip arts and many others.
Nowadays web designers understand that the content should be balanced with photos. As for pictures, they can be resized using different techniques. Resizing could be enlarging a photo with a graphic enlarger tool or downsizing photos using other type of software. Adobe Photoshop is the most commonly used software by web designers. However, there are other tools available on the internet that can be downloaded. Aside from downloading a photo enlargement or a resizing tool from the internet, the sites offer photo enlargement or digital photo enlargement services. These services are preferred by most digital photography enthusiasts because of the good quality products and prints that these online digital photo sites offer. This way you can save some money and get quality enhancements to your photos and prints.
Images like logos are most likely to be enlarged with one of the photographic enlarger tools available. If you decide to do your own digital photo enhancement and digital photo enlargements, then you should take note of the following:
1. Keeping the image definition or resolution. Especially for website photos, it is very important to keep the resolutions for more vivid pictures or images.
2. It is not enough to make an image or picture enlargement using the original file, also the sharpness of the image or picture should be preserved. The softwares algorithm and the correct interpolation technique chosen by the photographic enlarger are the factors that produce good quality enlarged photos and not fuzzy or pixilated. Take note that each Mega pixel photo has its digital photo enlargement limits. Going beyond will lower the quality of the enlarged photo.

2. Bilinear interpolation
With this method, the 4 surrounding pixels are smoothened and filtered to come out with sharper image, after which color is just applied to surrounding pixels.
3. Bicubic interpolation
This method involves analysis of 16 surrounding pixels. The results of the analysis are used for photo enlargements. This method guarantees good results and gives a clearer-quality enlarged photos and images. Smoother lines in the output image, compared to the original photo are also noticeable.
