How can i make a shortcut like this one:Click to view attachment in the TPA/Preset/System/menu , however with a different name such as this one- m5.png ?

Don't quite get whats in the file.

You want another link in your main menu? If so, download Svan's MenuEditor and then extract out your menu.ml from that location you mentioned.

Seems like the file you provided is a HOOK?

It seems to.
But if You will have normal png file, just set it as Left Small icon-it sometimes works, but not always!

This file contains the route to the icon as well the icon's name.What i've posted is just a short cut to the icon,whilst the real png.file is located in Other/Menu/Live.However when i edit this shortcut with Notepad the name of the icon from "icon1_selected" to "icon150_selected" the file cannot work,though renamed.So the question is how to manage to rename the file and to edit the file in a way that can be used?

Where do you want to put that link?

TPA/Preset/System/menu

er

as in where, in the phone.

main menu?

right softkey?

main menu

Then you edit MENU.ML in TPA/Preset/System/menu.

There's nothing to do with the file you attached.
