By default, the images that appear in the 'Mini Best Seller Layout' and the 'Mini New Product Layout' are not clickable. This is likely to be remedied in a later release of Actinic v8, but until then you can make the change yourself as follows.

Go to 'Design | Library | Layouts' and go to the 'Best Seller List Entries' group. Edit the layout called 'Mini Best Seller Layout'.

Locate the line of code:

<img style="border: 0;" src="ProductImageFileName" width="75" alt="ProductName" />

Replace it with the following code:

<a href="<actinic:variable name="SearchCGIURL" />?PRODREF=<actinic:variable name="ProductID" />&NOLOGIN=1<actinic:block if="%3cactinic%3avariable%20name%3d%22IsHostMode%22%20%2f%3e">&SHOP=<actinic:variable name="ShopID" /></actinic:block>">

<img src="<actinic:variable name="ProductImageFileName" />" width="75" alt="<actinic:variable name="ProductName" />" border="0"/>

</a>

You can also do the same to the 'Mini New Products Layout' located within the 'New Products List Entries' group in the 'Layouts' tab of the library.
