can you check http://wordpress.stackexchange.com/questions/48117/how-to-show-description-under-an-inserted-image/ this please. i have some question there.

Hi there,
not sure if someone still read this but in case you do: I have a question.

Your script works great but only if the description field is not empty!
I noticed the caption tag is completely stripped for images without a description.

Is there a workarround?
Thanx!!
