WordPress automatically creates thumbnails every time your upload a new image to your WordPress blog. It creates up to 3 different thumbnails files from one image even if you don’t need them. All these thumbnails created by WordPress automatically take up a huge amount of space on your server. If you don’t use thumbnails if can be a good idea to disable this annoying feature.
Another WordPress image related annoyance is that all uploaded images are linked to themselves by default, i.e. WordPress automatically adds a link to the source for every image. Fortunately, these two problems have one easy solution.
To disable WordPress thumbnails and image linking to the image source (link url):
Go to Settings->Media and uncheck all the boxes and clear all the values. Don’t forget to click Save change button.
