How do you upload photos into blog?
If you're using blogger.com, there's a function for you to upload your photos directly into blogger.
If not, you can also choose to upload your pictures onto an image hosting site and after that you'll just have to paste the HTML code into your blog.
Some image hosting sites includes image shack, photo bucket etc.
You can just create an account and upload your image onto the site and after that, you can share them online.
