I got asked how to make the profile picture in the About Me gadget bigger, unfortunately Blogger set this to default 80 x 80px. I searched around a found a way to edit this in order to make the picture bigger.
Dashboard > Edit Profile >Photograph >
and upload your photo, make sure it's the right size, as in make sure its a large image. Otherwise when we enlarge it, it will be pixelated!
Design > Page Elements > Add a gadget > Profile
Fill in your details and position it where you want on your blog in the Design > Page Elements.
You can see below that the image is small, so now we have to edit this.
To edit this, click Design > Template Designer > Advanced > Add Css & add the following code
You can edit this number to whatever suits you and your blog layout.
Then press enter & click apply to blog. You can see from the image below that my profile picture is now larger.
