OMG! Thank you so much for this! It solved a huge problem for me.
At first I received the error message that the file can't be found and realized the client had a space in the file name. Once I fixed that, it worked beautifully!
For the newbies, might I suggest that you explain somewhere how to use your sample codes in their site? I kind of guessed that this was how it was used and replaced your powerpoint code with my url and file name. But it might be helpful to others who don't understand that this is all you have to do.
But kudos for the plugin. You're a genius! And I thank you.
