Saat ini saya menggunakan Avatar Lokal Sederhana di beberapa blog saya yang memungkinkan orang mengunggah avatar khusus mereka sendiri.
Sejauh yang saya tahu Avatar Lokal Sederhana digunakan get_avatar
untuk memeriksa apakah avatar khusus dipilih, jika tidak default ke Gravatar.com.
Apakah mungkin untuk menonaktifkan bit Gravatar.com entah bagaimana, menonaktifkan Gravatar.com sepenuhnya dan mengembalikan hanya beberapa gambar host lokal jika tidak ada avatar khusus yang dipilih?
Saya harap tidak masalah untuk memposting ini di sini, tetapi ini adalah file Avatar Lokal Sederhana

Saya berhasil mengganti semua avatar gravitar.com dengan gambar avatar saya yang dihosting secara lokal dengan menambahkan ini ke
function.php
file tema saya :Ini mengasumsikan Anda memiliki avatar default lokal yang dipanggil
user.png
diimages
subdirektori tema Anda .Di
discussion settings
panel admin, pastikan "Tampilkan Avatar" dicentang.Saya belum mengujinya dengan Avatar Local Simple, tetapi berfungsi baik dengan Avatar Pengguna Dasar (yang merupakan garpu ringan dari Avatar Local Simple).
TIP : Jika Anda merancang avatar default Anda sendiri, saya sarankan membuatnya 300x300 piksel sehingga akan terlihat bagus di layar "retina" ketika WP menampilkannya di "150x150". Kemudian Anda dapat secara signifikan mengurangi ukuran file gambar dengan mengompresnya di tinyPNG.com .

Hapus avatar sepenuhnya. Masukkan kode ini di functions.php dari tema Anda digunakan.
