How do u add the pictures? To the post?
< a href="page to link to here">< img src="Picture here" width=350>< /a>
Make sure there is no space after each "<". If I don't put them, the html tag is not visible in this post.
<img src="link to picture here">
(without the width specified) will allow the picture to adapt to the full space it is given (page width) and thus works nicely on any device.
