Image url

There is a site https://therighthairstyles.com/ with an old version of Jetpack installed on it. Is there any possibility to save the URL of the pictures when transferring the site to another domain (for example https://www.screencast.com/t/nweTs3dSX)? If I install a new wordpress (on this domain therighthairstyles.com) and a new theme, but I will use the same images from the wp-content folder. Saver images url? And how to make the size of all pictures that will be on a single post be 500px https://www.screencast.com/t/906GessaY7EG
