Introduction

When it comes to blogging, user engagement is one of the most important factors that define the success of your blog. Comments are the heart of user interaction. However, Blogger’s default comment system shows either a blank avatar or the user’s Google profile image, which often looks outdated.

If you are running a modern blog with a stylish theme, you might want to show a custom avatar image for anonymous commenters or replace the default blank icon with a professional-looking avatar. In this guide, we will show you how to add avatar images in Blogger comments using HTML and CSS, step by step.

Why Are Avatar Images Important?

Better User Experience: Avatars make your comment section more visually appealing.
Professional Look: A custom avatar instead of the old Blogger blank icon gives your blog a modern touch.
Identity Highlight: Readers can easily recognize blog authors or frequent commenters.
Dark Theme Compatibility: Custom avatars can match your blog’s theme (light, dark, or neon designs).

Understanding Blogger’s Default Comment Avatar

By default, Blogger inserts an avatar image like this:

Here:

If the commenter is Anonymous, Blogger shows blank.gif.
If the commenter has a Google Profile, Blogger shows their Google avatar.

This means, for anonymous users, you can override blank.gif with your own image.

Method 1: Adding Custom Avatar Image for Anonymous Comments

To replace the default blank avatar in Blogger comments with your own custom image:

Go to Blogger Dashboard → Theme → Edit HTML.
Scroll to the <style> section (inside <head>).
Add the following CSS code:

/* Anonymous avatar ke liye custom image */
.avatar-image img[alt="Anonymous"] {
    content: url("https://i.ibb.co/wF41w5nX/images-11.jpg"); /* yaha apna custom image URL daalo */
    border-radius: 50%;   /* gol shape */
    width: 35px;
    height: 35px;
    object-fit: cover;
}


/* Custom Avatar for blank Blogger image */
.avatar-image img[data-src*="blank.gif"] {
    content: url("https://i.ibb.co/0pB6TP38/images-12.jpg"); /* yaha apni custom avatar link daalna */
    border-radius: 50%;
    width: 35px;
    height: 35px;
    object-fit: cover;
}

👉 Replace the link with your own direct image URL (PNG or JPG).

This will automatically replace the default Blogger blank.gif with your custom avatar.

Method 2: Adding Avatar for Specific Users

You can also show different avatars depending on the author’s name. For example, if you want to give the blog admin a special avatar:

/* Custom Avatar for Blog Author */
.avatar-image img[alt="YourNameHere"] {
    content: url("https://i.ibb.co/admin-avatar.png");
}

👉 Replace "YourNameHere" with your Blogger profile name.

This way, your comments will stand out with a unique author badge.

Method 3: Adding Dark-Themed Avatars

If your blog uses a dark theme, normal avatars may not look great. Instead, you can use dark-mode avatars. Example:

.avatar-image img[data-src*="blank.gif"] {
    content: url("https://i.ibb.co/dark-anon.png");
    background: #111;   /* optional dark border */
    border: 2px solid #444;
    border-radius: 50%;
}

This ensures your comment section matches your modern UI.

Method 4: Premium Avatar Pack (Multiple Designs)

You can even assign different avatars randomly or based on user type (Anonymous, Registered, Author). Example:

/* Anonymous Avatar */
.avatar-image img[alt="Anonymous"] {
    content: url("https://i.ibb.co/anon1.png");
}

/* Registered User Avatar */
.avatar-image img[alt="User"] {
    content: url("https://i.ibb.co/user1.png");
}

/* Blog Owner */
.avatar-image img[alt="AdminName"] {
    content: url("https://i.ibb.co/admin1.png");
}

Extra Tips

✅ Use PNG transparent avatars for the best result.
✅ Host images on ImgBB, Postimages, or Blogger itself for reliability.
✅ Keep avatars small in size (under 50KB) to avoid slowing down your blog.
✅ For mobile-friendly designs, keep width around 35px–45px.

Conclusion

By default, Blogger shows a blank avatar for anonymous comments, which doesn’t look professional. With a few lines of CSS, you can replace that with your own custom avatar image, whether it’s a stylish dark theme icon, a premium pack avatar, or even a special admin badge.

This not only improves the visual appearance of your blog but also gives a modern and professional touch to your comment section.

✅ Now your Blogger comments will no longer look boring. Instead, they will feature modern avatar images that match your site’s theme.
