質問: ie8は.png画像を表示しません ユーザーがこれをどのように行ったかは本当にわかりませんが、何らかの理由で.png画像がie8で機能しなくなりました。.png画像が含まれているページを表示すると、小さな赤いxとして表示されます。画像に直接移動すると、小さな赤いxも表示されます。私が試してみました: ie8を再インストールします。 ie8の設定をリセットします。 別のユーザーでログインして、.pngが正常に表示されるかどうかを確認します。 ウイルススキャンの実行。 malwarebytesの実行。 spybot search anddestroyを実行しています。 hijackthisを使用して一般的ながらくたを削除します。 マシンを再フォーマットすることもできますが、それよりも問題を修正したいと思います。osはwindows xp sp3
