Okay, I am too much of a Flash novice to even get this to work! :(
I tried changing the format of the text boxes in the fla file, to no avail (yes, I cleared my browser cache and copied the published viewer over, etc.)
Surely there is a simple way to do this in the gallery.xml file--or, more to my liking, in the Picasa xml template files.
For example, the imageNode.xml file currently has:
<image>
<filename><%itemName%></filename>
<caption><%itemCaption%></caption>
</image>
And the header.xml file has:
<?xml version="1.0" encoding="UTF-8"?>
<simpleviewerGallery maxImageHeight="400" maxImageWidth="400" backgroundImagePath="../../../images/backgroundblue2.jpg" textColor="0x000000" frameColor="0xffffff" frameWidth="10" stagePadding="10" thumbnailColumns="5" thumbnailRows="4" navPosition="left" title="<%exportDescription%>" enableRightClickOpen="false" thumbPath="thumbnails/" imagePath="" >
I tried following the FAQ and putting in the html thus:
imageNode.xml:
<image>
<filename><%itemName%></filename>
<caption><center><%itemCaption%></center></caption>
</image>
header.xml:
<?xml version="1.0" encoding="UTF-8"?>
<simpleviewerGallery maxImageHeight="400" maxImageWidth="400" backgroundImagePath="../../../images/backgroundblue2.jpg" textColor="0x000000" frameColor="0xffffff" frameWidth="10" stagePadding="10" thumbnailColumns="5" thumbnailRows="4" navPosition="left" title="<strong><%exportDescription%></strong>" enableRightClickOpen="false" thumbPath="thumbnails/" imagePath="" >
Thinking I had the brackets in the wrong place above, I also tried this for the header, but it broke the movie:
<?xml version="1.0" encoding="UTF-8"?>
<simpleviewerGallery maxImageHeight="400" maxImageWidth="400" backgroundImagePath="../../../images/backgroundblue2.jpg" textColor="0x000000" frameColor="0xffffff" frameWidth="10" stagePadding="10" thumbnailColumns="5" thumbnailRows="4" navPosition="left" title="<<strong>%exportDescription%</strong>>" enableRightClickOpen="false" thumbPath="thumbnails/" imagePath="" >
I also looked at the FAQ and found out about the CDATA tags for the captions (I also tried removing the brackets around %itemCaption%, which broke it):
<image>
<filename><%itemName%></filename>
<caption><![CDATA[<font align="center"><%itemCaption%></font>]]></caption>
</image>
and also tried:
<image>
<filename><%itemName%></filename>
<caption><![CDATA[<center><%itemCaption%></center>]]></caption>
</image>
Okay, I am done with the trial and error! :) This is enough information to get help from the experts, I hope. (Please and Thank-You!)
