Follow these quick tips for using images on your church website and you'll have a site that loads quickly and looks great. First, there are a few things you need to know.
Image Dimensions: Digital images are composed of a large number of individual dots called pixels. Every digital image can be measured in terms of pixel width and height. When you look at the information or properties of an image on your computer and you see something like this (Dimensions 3600 x 2400) you are looking at the pixel dimensions of the image. In this case, the image is 3600 pixels wide and 2400 pixels high.
Image Resolution: The resolution of an image is measured in dots per inch (dpi) for print images or pixels per inch (ppi) for images viewed on a computer screen. While not technically the same, the terms dpi and ppi are often used interchangeably. The most common resolution that you will find for images on the web will be 72ppi. This is due to the simple fact that this is the best resolution that can display on the vast majority of computer screens.
