Change USP Panel Button?

I'd like to chnange the USP Panel button with one of the images below (I have a .png and .SVG). Which should I use and how might I do this?

Well, there's a lot of ways to go about doing this, but this is the way I figured out first, and as such, has been the way I've stuck with as long as I've been using Ubuntu.

the default GNOME Applications menu logo is here:``` /usr/share/icons/hicolor/48x48/apps/distributor-logo.png

these are the steps that I follow to set up a symlink that points to whatever menu icon i happen to want that day:

cd /usr/share/icons/hicolor/48x48/apps/ sudo mv distributor-logo.png distributor-logo.old.png ln -s ~/.pixmaps/menu-icon.png distributor-logo.png cd ~ mkdir .pixmaps

then it's just a matter of copying/moving the new graphic to ~/.pixmaps/menu-icon.png ... once it's in there, to see your new graphics on the panel, enter this into your terminal:

killall gnome-panel

You can try substituting .png for .svg in the **ln -s ~/.pixmaps/...** line, I'm pretty sure that works.  

For a more flexible solution, you can insert the graphic into one of your icon themes...

try to:

cd ~/.icons/*InsertThemeNameHere*/scalable/apps/

if you get an error saying that the dir isn't there, do this:

mkdir ~/.icons/*InsertThemeNameHere*/scalable/apps/

then, to copy the file into the theme:

cp LinSta_Start_Button.svg ~/.icons/*InsertThemeNameHere*/scalable/apps/distributor-logo.svg

From here, you can either switch your icon theme to something else, and back again, or:```
killall gnome-panel

Anyway, hope this helps... Lemme know if you have any problems.

Tried the second option, the image was tiny. I'll keep tryin' though. Thanks! :D
