In a previous post I gave some tips on using HTML to enhance you blog posts. I've since discovered a few more supported html tags.
bolded text - <b>bolded text</b> italicized text - <i>italicized text</i> underlined text - <u>underlined text</u>
(please note that these are depreciated tags and I have just used them as an example as they are very short and easy to use. In real webdesign they wouldn't be used.)
More interesting is that you can use images:
code: <img src="web address of image" />
This to include your own simply insert the web address of your image with the url of your image.
To put images on the web and get the code made for you check out imageshack
Better still use flickr.
Why not put an image in your biography?
As always any questions just post a comment.
