adding images to WordPress

Images include photographs and other kinds of images.  Aside from the obvious appeal of images, they can also increase a website’s and a post’s searchability on search engines such as Google when tagged properly.  People are more likely to read a post with images.  The more people reading your posts, the more “reach” you have.

Fast Facts:

Image Size Affects:

  • page or post loading speed (smaller means faster)
  • storage space on your server/webhost (smaller means more)
  • the number of photos you can upload (smaller means more)


Images are measured in 3 ways:  pixel height/width, size in KB (or MB), and resolution.  The maximum upload size for the WordPress Media Library, is 20 MB (20,480 KB).  Unless you are uploading a photo with great detail, a resolution of 72 ppi (pixels per inch) will produce a “lighter” image.  You should aim for something under 100 KB.  72 ppi is an adequate resolution because that is what browsers display.

So, smaller is better, right?

Well, almost always. There are times when better quality from a higher resolution images is important.  For example, one of my clients is a Silversmith and displays his silver engraving on his website.  It is possible to work around this by having a smaller image load first, then provide the option to click on a larger, higher resolution image so that the fine engraving detail can be showcased.
