ヘッダーがドアップなのですが…
-
国外有料テンプレートを使っています。
ヘッダー画像が凄くアップになってしまいます。
ピクセル変更(800px前後)なども試しましたが直りません。
きっとphpファイル自体の影響なのだと思いますが、違うのでしょうか？
どなたか解決して頂けますか？変更するのは、header.phpなのか、functions.phpなのかも分からない程に無知です。
どこをどう修正したら、解決出来ますか？（下記に、header.phpとfunctions.phpのファイルを添付します）

*
* The upload URL path is set either by the ‘upload_url_path’ option or by using
* the ‘WP_CONTENT_URL’ constant and appending ‘/uploads’ to the path.
*
* If the ‘uploads_use_yearmonth_folders’ is set to true (checkbox if checked in
* the administration settings panel), then the time will be used. The format
* will be year first and then month.
*
* If the path couldn’t be created, then an error will be returned with the key
* ‘error’ containing the error message. The error suggests that the parent
* directory is not writable by the server.
*
* On success, the returned array will have many indices:
* ‘path’ – base directory and sub directory or full path to upload directory.
* ‘url’ – base url and sub dire
