[RD] Code:prevent guest img-postng stopped working

I just did a test and for reasons unknown (as yet) the following line in that code is not returning the expected result:

function removeImg() {
var re = mes[0].innerHTML;
re = re.replace(/\[img(.+?)?\].+?\[\/img\]/gi,'')
mes[0].innerHTML = re;
}

After ruling out the usual event and global variable naming conflict (two codes by Ross are actually using the exact same name for a variable), the only thing I can see is probably the non-standard method of accessing the textarea contents. So try changing that red line to

var re = mes[0].value;

I should have given you two mods.
This line which is 2 lines below the red line in my previous post would also need to be converted from innerHTML to value

mes[0].innerHTML = re;

change to:

mes[0].value = re;
