Menu Image, Icons made easy

This plugin delivers exactly as promised!  I highly-recommend.

Very functional - Does exactly what it promises!

Works really well, but the plugin spams the WP Admin with 'upgrade' messages and once dismissed, they come back again and again.

Works, but constant messaging in admin


Tried a couple of plugins for adding menu images, so far only this one worked for me.



Also the support is top-notch.



Overall a 5-star plugin!


Best plugin so far

Adds an image or icon in the menu items. You can choose the position of the image (after, before, above, below) or even hide the menu item title.
