I'm developing an extension for Photoshop CC and I'd like it to have a custom icon in Extension Manager. Is there xml that I can add to the manifest.xml file to add the custom icon?
Note: I already have custom icons for the extension within Photoshop, I just need help with the custom icon in Extension Manager. I want to replace the puzzle piece in the attached image.
You said manifest.xml, I suppose you are developing a CSXS extension (without mxi file in the extension). Extension Manager doesn’t support to show custom icon for CSXS extension. For ordinary extension (with a mxi file), you can have a custom icon, please refer to
http://helpx.adobe.com/extension-manager/kb/general-mxi-elements.html#id_16898. You can make a hybrid extension based on your current CSXS extension. i.e., create a mxi file, specify the custom icon and the current CSXS extension in it, then package it as a hybrid extension.
