Hello,
I use the frontend editing page for the members to post. Under the image tab on frontend edit, I need to hide the "Browse server button" so all register members cannot access to the server file. What would be the best way?
Thank you.

Maybe one way but, not the safest is to hide input field and button with css:

<input type="text" name="existingImage" id="existingImageValue" class="text_area" readonly=""> and

<input type="button" value="Browse server..." id="k2ImageBrowseServer">

@Victoria

When used in front-end the media manager has read-only permissions so this is not an issue to worry about.

There is no option to disable media manager in front-end. You can hide the button using CSS code:
Note that this code just hides the button. If the user knows, he can still type the URL of the media manager and open it.

Thank you!

You are welcome.
