Hi After searching on the web i was able to fix the Uploader just by changing the layout file of resolution slider by adding the few line in the file as shown in bold
file : app/design/adminhtml/default/default/layout/am_revslider.xml
-------------------------------------------------------------------------------------------------------------------
<layout>
<revslideradmin_slider_index>
<reference name="content">
<block type="revslider/adminhtml_
slider" name="revslider_slider"/>
</reference>
<action method="addJs"><name>lib/uploader/flow.min.js</name></action>
<action method="addJs"><name>lib/uploader/fusty-flow.js</name></action>
<action method="addJs"><name>lib/uploader/fusty-flow-factory.js</name></action>
<action method="addJs"><name>mage/adminhtml/uploader/instance.js</name></action>
<action method="addJs"><script>mage/adminhtml/browser.js</script></action>
<revslideradmin_slider_import>
<reference name="content">
<block type="revslider/adminhtml_slider_import" name="revslider_slider_import"/>
</reference>
</revslideradmin_slider_import>
</layout>
