This plugin to save as .ico in photoshop has been around for a while, but I can't seem to make it work for CS6. According to this question in the Adobe Forums, the plug-in works if installed in
C:\Program Files\Adobe\Adobe Photoshop CS6 (64 Bit)\Required\Plug-Ins\File Formats but it's not doing anything. Do you know of any alternative plugins for CS6? I'm using win seven 64 bits.
EDIT: The plugin does work, just not for images that are bigger than 256 x 256px.
