Failed to load resource: the server responded with a status of 404 (Not Found)

404 (Not Found)は、ファイルが見つからないという意味。
推定原因は、2つあるらしい。

①ファイルがデータベースに保存されていない
②画像がDBに保存されているけど、パスがずれてる

ファイルは保存できていた。なので、原因は、②。
参照記事:https://teratail.com/questions/3951

###パスの確認

views/user/show.html.erb
<img src="<%= "/img/#{@user.id}"%>">

##解決策
/img/#{@user.id}に、jpgを付け加えてみたら、パスが特定されて、無事画像が表示された。

views/user/show.html.erb
<img src="<%= "/img/#{@user.id}.jpg"%>">
