Hello,
First of all I like to thank you for this great tool.

I have a problem with the space between the pictures.
1. It is not possible to change the space.
2. Between some pictures the space is smaller.

could you please have a look

Anyway, another question is, can I add a border for the pictures?

Thanks in advance.

@1 it is.
@2 I see that, don't know why. Will have to be fixed in a future version.
@3 use the costume css field in the module parameters.
