Not her screen name but her id (BHID) and goes here : " Big_Host_ID=NumHost&bhid=BHID-HERE " ! You need to change only three things in that iframe : WL domain name , Model ID and affiliate WID !
So for OP's feed the iframe for the first model in the list will be :
Code:
<iframe src="http://pcash.imlive.com/releasese/activepage7139.asp?type_page=white_label&domain=livemilfwebcam.com&Big_Host_ID=NumHost&bhid=8843525925&host_next=1&wid=12345&ptype=1&queryid=&twidth=900&theight=560&lfwidth=70&bgcolor=&tcolor=&seccolor=&btntext=&btnt_size=&btnt_clr=&btnbg_clr=&offtext=&ptext=&etext=&msgt_size=&msgt_clr=&msgbg_clr=&timer=45" width="900" height="560" frameborder="0" scrolling="no"></iframe>
