Image on component

Hi Guys,

I am thinking of having a custom preview component which recieves a list of data(let say list of object cross section) and one index(say i) and then component shows that object on itself.something like this:

the list is a list of let's say .png or .bmp or whatever files, and second is an integer which is an index pointing to one member of the list.then component read that file and show it on component box ...

I was wondering how it is possible?

Thanks
