DP Comments is a simple widget to display latest comments with user avatars:

The configuration of the widget is really simple:

As you can see, there are three important options:

• Avatar size – this option is used to specify the size of the avatars displayed under each comment.
• Word count – this option specifies the maximal amount of words displayed in each comment item.
• Number of comments – it specifes the maximal amount of comments to display.

The DP Comments widget uses a built-in WordPress cache system and it refreshes the cache after every comments operation.
