The helpful advice I recieved so far said I need to add a class attribute to it in HTML(then select and override this in CSS)
But I'm unsure how to effect this;
These are the steps I've taken so far:
1.I inspected the image with fire bug(the first one on the page); got the following HTML:
<img height="214" width="300" alt="" src="http://deardot.com/wp-content/uploads/2012/08/hay-bales-julie-lamons4-300x214.jpg" title="Hay bales" class="alignnone size-medium wp-image-921">
Now I believe that I need to add a class attribute to the image: I'm not sure how I do that please?
