Shoutbox

The file msgres_4004_1001.txt is the UIFile (user interface file) which builds the graphics included in the contact list.

You must copy this file into your skin's folder and then edit it to include a new element whereby you reference the picture id 59000.

This numbering system is the way to include new pictures in messenger (rather than replacing existing ones).

You have to include a new picture in your skins folder and then set it to picture id 59000 in your SkinInfo (as shown in the documentation)

The definition file must then be replaced in the SkinInfo (so that the new, edited one is used and not the original) using the code you have already displayed.

If you need more help then try looking at a skin which does replace the contact list background (such as my skin, linked in my signature) and look at the relevant sections of SkinInfo and the definition file to try to work it out
