Thanks for the quick responce...
to Valentin Nedkov:
I have session_start() on another page. Session start gets band_id as a
value when user logs in.
I've tried to echo session variable on show_pic page and it works.
And I belive that I can't set default value for band_id because the picture
I want get is depended on who has logged in.
to Jason Pruim:
when I look at what show_pic shows, it's whole lot of this:
ÿØÿà�JFIF��N�N��ÿÀ��âŠ�ÿÛ�„�.....
When I used plain number or WHERE band_id='{$band_id}' those weird
markings(above) were identical. (They were different when not using these '{
}' )
And the code works with plain number so we must be closer to the truth now..
to David Robley:
band_id is set to session variable when user logs in...
