Graphics, Figures & Tables ⇒ Add pictures at bottom of a poster

[ZzAlex]

Hi,
I am trying to make a poster using baposter class. I took a model on internet that corresponds to what I want to do but I would like to put pictures below the blocks at the bottom of the poster and I have no idea how to do this.
I think I must define a different size for the blocks so that I can put the pictures at bottom.

Here a link to the model of the poster I am using.

Thank you for any idea.
