Images uploaded and showing indirectly but not showing directly

Salam,

hope u will be fine, i am facing a problem and did not find any way to resolve it. i have uploaded whose link is:

https://it-aroma.com/wp-content/uploads/choose_domain_name.jpg (first open this link)

when i open this link it is giving 404 error, but now visit the link below:

https://it-aroma.com/?attachment_id=721

and click on domain image below adsense ad, image opens now with the same url which was giving before 404 error, please check what is the problem.
