1. Create your image. I personally use Photoshop for that. If you don’t have Photoshop available there are plenty of other tools online. But I suggest you use Photoshop because it’s very basic stuff to do. I will also make a tutorial about it as soon as I get the time for it. My signature's dimensions are 250x140. Which is fine for me. I wouldn't go for less but it does depend on what you seek so you can experiment about it.

Now as a part of this tutorial if you need help creating your signature on Photoshop, or you don't have Photoshop and want to make it there, leave a comment or contact me via mail and I will make your signature based on your guidelines!

2. Upload your image to an image host site. I used imgur which makes it very easy and fast. There are many more of course if you like such as, postimage and tinypic so feel free to use any.

3. Use the DIRECT LINK of your image by copying it with CTRL + C and post in the area I highlighted for you in step 5.

4. Login to your blogger account and go to Settings>Post and comments.

5. In the box that says Post template click and and paste the code but replace the highlighted with your own direct link of the image. The way I have it is for the image to be centered.

6. Click save and that’s it! If you had any previous posts you will have to post it manually but for the future you will always have the signature on your post.
