How to remove the borders of pictures at Blogger

Sometimes taking the borders of the images creates a very interesting atmosphere and it is very easy to get rid of them.
At the "edit html" add the code style="border:none;""display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" 
You must do it before writing or adding other images at the post otherwise you can lose the edition of the whole post. It took a while to figure out why I was not doing it correctly.
You can find at this blog done by Peter Enviroment lots of answers for some Blogger problems. Have a great week!
