Now you don't need to remember and rename the theme files. Just edit the theme descriptor.xml with opera mod or with mini commander. You can get them at java softwares section. With opera mod open text iso from operation menu. You will see the icon name and its id like menu item= gallery item id= gallery.png just like that replace the item id with your own file names ex. Menu_bg.jpg with michael.jpg just replace item id. Now pack your files with that theme descriptor file after editing it. You can get theme descriptor file details by pressing back button. If you have any problem tell me by sending an email at sam.shendre@gmail.com .
