I already have the solution. This perhaps will become Worpress consideration for the next update’s, because I was found the solution in WordPress forum about 4 years old topic’s, and the problem still the same. WordPress automatically generate three images and also the theme we used generate four to seven images, that will drain hosting disk space.
The solution is:
1. Login To Your WP Dashboard.
2. Go to Settings and then, Media.
3. Here you will find 3 various image sizes: thumbnail, medium, large. Decide which image sizes you won’t be using and then set those sizes to 0.
4. Update and save your new settings.
