When first designing a website, one seldom begins with the images and content used in the finished product. The layout and overall look of the site is much more important initially. It is often a fluid and rapidly changing process. Stock images can be useful but they must be cropped to the right size.
As the layout changes, so can the dimensions of the images. Time spent locating, re-sizing and replacing images that will never be used is time better spent refining the layout.
This is exactly what image placeholders can do for you. By automating the selection process, the image placeholders provide a range of customization options that can include size and color, text, multiple file types, preset sizes and even themed images.
It is simply a matter of a few clicks and you have an image that is the right size and type you need. You can quickly get back to designing. An image placeholder service lets you automatically use a random image of the correct size with minimal effort.
I have compiled a list of what I consider the most flexible and useful image placeholders available on the web. Check out the options available with each one, see what works best for you and I am sure you will find one or two image placeholders for use on your own projects.
