বর্তমানে আমি আমার বেশ কয়েকটি ব্লগে সাধারণ স্থানীয় অবতার ব্যবহার করছি যাতে লোকেরা তাদের নিজস্ব কাস্টম অবতার আপলোড করতে পারে।
যতদূর আমি জানি সরল স্থানীয় অবতারগুলি গ্রাভাতার.কমের get_avatarডিফল্ট না হলে কোনও কাস্টম অবতার নির্বাচন করা হয়েছে কিনা তা যাচাই করতে ব্যবহার করে।
গ্রাভাতার ডট কমকে কিছুটা অক্ষম করা, গ্রাভাটার.কমকে পুরোপুরি নিষ্ক্রিয় করা এবং কাস্টম অবতার নির্বাচন না করা হলে কিছু স্থানীয় হোস্ট ইমেজ ফিরিয়ে দেওয়া কি সম্ভব হবে?
আমি আশা করি এটি এখানে পোস্ট করা ঠিক হবে তবে এটি সাধারণ স্থানীয় অবতার ফাইল হবে
