Is this possible without hacking the code?

I want to force my users to only upload using "Files and Images" tab until they are a bit more established.

Many thanks
Martin

Alright,

take a look at... http://api.silverstripe.org/trunk/forms/fields-formattedinput/HtmlEditorConfig.html

I use..

HtmlEditorConfig::get('cms')->insertButtonsBefore('formatselect', 'fontselect');

...in my _config.php to *add* something, maybe one of the other functions like "modifyButtons" might help?

Well, i think i've got a rather hacky solution:

1. create a file hideUpload.js in mysite/javascript/ with this code:

(function($) {
    $("#Form_EditorToolbarImageForm p.showUploadField").hide();
})(jQuery);

2. add this line to your mysite/_config.php

LeftAndMain::require_javascript('mysite/javascript/hideUpload.js');

This will hide the the image upload thingy from your users.

Cheers,
Christian
