    artist and track on seperate lines?

    Is there any way to edit the ScrobblerSig code so that the artists and tracks appear on their own lines? I'm trying to squeeze the image into a sidebar on my blog, and when the artist/track are on the same line, it often extends past the horizontal space I've got.

    Also if it's possible to put the "last track played" message and the time/date on separate lines as well... making a total of 4 lines of text in the image.

    I'm running the script from my own server, so I've got the control for whatever needs to be done to make this work. Unfortunately I don't know php!

    Thanks in advance.

    Here is a really simple way to do it.

    /* ---------- Main User Config ---------- */

    /*
    * The options that are listed below may be specified in the url if the allowParameters option is
    * true. To do so first append a question mark ? to the end of the url. Next, specify the option
    * name followed by an equal sign = and then the value; for example, option=value. Multiple options
    * are specified by separating them with an ampersand &; for example, option1=value1&option2=value2.
    * Enter %26 to specify an ampersand & character in the url, %3D for an equal = sign.
    *
    * The username option is an exception and is always allowed to be specified in the url, but whether
    * or not it is actually used depends on other options.
    *
    * All parameters may be specified by their regular name or by a short form; the short form that can
    * be used is specified in parenthesis at the beginning of the parameter's description. The general
    * naming convention for the short name is to use the first letter of each word comprising the name.
    * Be aware of conflicts though, such as backgroundColor (bc) and borderColor (bdc). Whether the
    * full or short name is used specify the parameter name in lowercase.
    *
    * Examples
    *
    * scrobblersig.php
    * scrobblersig.php?fontsize=24
    * scrobblersig.php?labelcolor=aa0000&trackcolor=a9b200

    Thank you so much! It worked like a charm :D

    The only problem I'm having still is that it never seems to want to use the "currently playing" text. Even when the song it lists is one that I'm listening to at that very moment, it still displays "last song played" and then the time/date. Are there any obvious explanations for this, or could it just be the free server I'm using not updating fast enough (100webspace)?

    Thanks again for the php code!

    Well the scipt chaches the data for so long. You cna edit the time on the line which shows "$cacheDuration = 120;" however it is not good to set too low as it puts strain on the last.fm site. The 120 means 120 seconds or 2 min.

    The "current playing" text only worked on the old RSS feed and back in the old days when there was such a thing as "Currently Playing". Last.fm has an artifical "Now listening" on your profile page but that is not transferred to the feed like it used to; so your sig will never use that, because it never things any of the tracks are "currently playing".
