i am using tinyMCE 3 for my project. Unfortunately image upload option is not by default. I am trying by adding some code, but its not working with tinyMCE v3. See its not giving option to browse image.
Here is what i am doing :
tinyMCE.init({
mode : "textareas",
theme : "advanced",
plugin : 'imgmanager',
theme_advanced_buttons1 : 'imgmanager'
});
But its not working for me.

Like my comment you are not pressing the correct button (probably you have not configured correctly
tinyMCEand it is not displaying your plugin's button) Below is the configuration that worked for me:Notice
pluginis wrong, it should bepluginsOf course make sure you have copied the
imgmanagerplugin to yours tinyMCE installationpluginsfolder.Here is a screenshot of mine:
The plugin button is on the upper left corner.
