doesnt inserts images?

Hi, first of all. Thanks to the developer of this plugin for his great work and effort!
i am writing because i need a plugin that allows me to insert one image in a created module.
i have try with a couple of plugin… they doesn’t seem to work, i haven’t been able to find one that works with this plugin…
The last one i tried is called Simple Image Widget…
i am able to find it in the widget window list… but after it opens… i press select picture and nothings happens….
i have tried the widget in the page and it works just fine… but when trying to use it inside the widget window of the page layout builder I does nothing…
So maybe this plugins are not compatible… can anyone recommend a plugin for image insert? no sliders, i want to insert just one image… as simpler the plugin, the better is for me.
Thanks

i have the wp 3.6.1 and the directorypress theme
