It sounds like you are new to foobar. In that case it's worth it to do some reading and understand how everything works.
Here is the foobar2000 wiki -
http://wiki.hydrogenaudio.org/index.php?ti...2000:Foobar2000You probably want to start with the scripting tutorials section to understand how things work within foobar (Brother John's is a good one to start with). Then you can check into the foobar2000 0.9.x Components section. There you can find component specific wiki's both for trackinfo_mod and single_column_playlist. Those will show you how to work with the component specific functions. If after that you have some more questions post back and we can help you some more. Right now you don't understand the scripting behind foobar and that will make it very hard to help you.
Since I was curious already, here's some sample code to tile an image as the background in your playlist. You'll understand what it all means after you finish some research. This code assume the image has a 1.25:1 aspect ratio.
CODE
$puts(NumRows,$div($muldiv(4,%_width%,5),%_height%))
$puts(RowNum,$mod(%list_index%,$get(NumRows)))
$puts(Ypos,$mul($get(RowNum),%_height%))
$imageabs2(%_width%,$muldiv(4,%_width%,5),0,$get(Ypos),%_width%,%_height%,0,0,'/components\default.jpg',nokeepaspect alpha-100)
