Increase Image Height for Block #5 Imgaes?

Hello,

Unfortunately there is no option for it in the theme panel, You will need custom work to do it.
You can change the thumb size used by the block by identifying the module file used by it. In this case it’s module 3: http://screencast.com/t/f4EDZUpfC7yJ
You can change the thumb size to another used by the theme: http://screencast.com/t/DsEsN5vR53Bl
But this will cause further problems: http://screencast.com/t/OthxWLXR6Z Images will stretch over the titles so it will need further adjusting to display properly.
I used the 534×462 thumb size. You can use this custom css in the theme panel->custom css to get the titles a bit lower:

.td_module_3 .td-module-thumb {
height: 275px!important;
}

I hope this helps.
Thank you!
