Understanding the basics of online imaging may help you prepare and understand what you will see online. The highest resolution displayed on a computer monitor is 72 pixels per inch. It does not matter how high a resolution your images are scanned, you will only see 72 px per inch. If you are scanning your own images, please scan at no higher than 100 px per in. The added resolution will be wasted, and it adds to the file size of the image.
File size is very important to the speed with which images load on a website.
Research shows that viewers will not wait for slow loading images. You will not be able to sell your product if the image loads too slowly and no one waits to see it. All images for websites will be optimized to retain the best quality while reducing the file size for fast loading. It is important to realize that on the internet, no two computers see exactly the same image. Browsers display colors and formatting differently, and everyone sets their monitor to slightly different brightness and color readings.
