You have to hit the A for advanced editor and then the photo button, copy the embed code and paste into there. Works fine doing that, that's how I did all my PB pics too.
Got these from work, and i think im going to use them,, didnt hold water overnight, bathed in gas oil, didnt melt or break down,, large panel is 1.5 x 16 x 24 floated 19 lbs,, and sumberged at 22 lbs..
if i did my calculations right, with the large panels 74 of them + or - and the smaller ones, 49+- assuming the small one float 15lbs, and the large ones 20 i have enough flotation for 2215 lbs....now where to fit them all.. i dont think they will all fit....
