SOLVED: Comment user icons linking to the commenter's icons page

[london_fan]

Hi there, yet another newbie at DW here. I recently imported my highly customized Flexible Squares layout here with layout and theme layers. I changed around the bits that needed tweaking, but I got stuck on one thing. On LJ I have customized code for all icons (the 100x100 ones, not the 16x16 user icons in front of the user name) to link to the respective user's icons page. The link for entry user icons looks as follows:

<a href="$*SITEROOT/allpics.bml?user=$e.poster.username">

And this is the link for the user icons in comments:

<a href="$*SITEROOT/allpics.bml?user=$comment.poster.username">

Due to the different structure of the link to users' icons pages on DW, those links don't work here, but I'm stuck figuring out how to change them. For entries it seems to work just fine to replace the whole link with "icons", because DW will pull up the respective "username.dreamwidth.org/" part all on its own, but that doesn't work for the comment user pictures. How can I create a link to comment posters' icons pages?

Any help here would be highly appreciated.

ETA: Many thanks to chagrined for solving this and showing me how to break up link strings!
