How to insert a text content
Simply write your own text, html tags are allowed.
See some example below:
bold : <b>bold</b>
italic : <i>italic</i>
color : <font color="red">color</font>
You can also use some PHP code inside, this is not always avaible on some servers due to security reasons.

If you uploaded an image you can link it with the standard html tag. For example, if you've uploaded the image test.png into your blog whom id is sample you have to write:
     <img src="./blogs/sample/uploads/test.png">
You can also set your html tags as explained by w3c standard.

How to insert a link
