hello

i writed this code part for wordpress :

<?php $av_id=bp_get_group_id();?>
<div class="img_group" style="background: no-repeat url('<?php echo(bp_core_fetch_avatar('item_id='.$av_id.'&object=group&no_grav=true&html=false'));?>');" ></div>

in my google chrome code inspector i have this html output :

<div class="img_group" style="background: no-repeat url("http://localhost/001-blueprint/wp-content/uploads/group-avatars/2/5f3252e75e000-bpthumb.png");"></div>

and i have this css line in my chrome inspector too, i have image miniature on flyhover so image seems to be charged.

element.style {
    background: no-repeat url(http://localhost/001-blueprint/wp-content/uploads/group-avatars/2/5f3252e75e000-bpthumb.png);
}

problem, i don’t have anything on my website …
