Want to remove Image Boundries but also have a caption ...

[selectams 2]

Hi, I am using iBlogpro (latest version) and if i add a caption to an image - a grey boundary is formed around the image. I would like to either get rid of the grey boundary or change the boundary colour to white. Very to new websites, css and html. Look forward for your advices
