You may notice that some images look blurry or pixelated after installing a new theme. To fix this, you should regenerate your site's thumbnail images whenever you install a new theme.
How to regenerate your site's thumbnails
1. Firstly, you should go to Settings > Media in your dashboard. Check that the sizes are set to the numbers shown below:
2. Go to Tools > Regenerate Thumbnails
Leave all the settings as their default options.
3. Click the "Regenerate Thumbnails For The x Featured Images Only" button
Regenerating your site's thumbnails might take several hours if you have lots of images. You may wish to leave it running in a tab whilst you work on the rest of your site. You can edit any other section of your site whilst the process is running in the background.
