Making a blog button is really easy, anyone can do it, here is how I make mine.
1. First you need to create a logo or find a picture to represent your blog. You can do this in any photo program such as paint, picasa or my favorite photoshop.
2. Upload your graphic to photobucket, if you don't have a photobucket account it's free to sign up. Once your picture is uploaded, go to edit, resize and change the dimensions to 125 x 125.
3. Copy and paste the code below into notepad. Change the bold type to your web address and the direct link to your photo in photobucket. To get this link: click picture, share, get link code, then copy the direct link code and paste it in the spot below.<a border="0" href="Your Web Address Here" target="_blank"><img src="Direct Link to PhotoBucket Here" /></a>
<textarea cols=”15″ rows=”4″ wrap=”virtual”><a border="0" href="Your Web Address Here" target="_blank"><img src="Direct Link to PhotoBucket Here" /></a></textarea>
4. Copy all that code and paste into your add html widget in blogger. It should look like this when you're done, with a text area below the button. If you just want the button without the grab html code below then only copy and paste the first line of code into your html widget.
