Not sure what you want to do but you can check the examples page to see what could be done with jqGrid (http://trirand.com/jqgrid/jqgrid.html)

Hi.

Credit for this answer goes to Tony for he mentioned it in an earlier thread.

For waht you want you could possibly use tree grid for folder structure and for the pictures and all else needed, just pass the html source through the server response.

For example.

colNames: ['Item','Image','Price'],
colModel: [ name:"item",index:"item"....},
