However, the name may only contain the letters A-Z and may not be longer than 30 characters. This was defined to recognize template variables (e.g. <!--%IMAGELOOP%-->) more secure in the source files.
These are used in the content of the special tags.
The following inline variables are supported:
%IMG% for the thumbnail image
%IMGMINI% for a small 150*150 pixel preview
%IMAGE% the actual image file
%MASTER% the unprocessed file as attachment
%IMGYYY% year the image was taken
%$NAME% other, self-defined variables - only if parameter checkvar="1
%LINKMASTER% creates a complete link to the original file - if activated using INCMASTER and used with registered version of fotoARRAY
%LINKJPEG% creates a complete link to a large JPEG - if activated using INCJPEG and used with registered version of fotoARRAY
loop="1" "1" is required for the variable to be used as a loop
edit="0" "0" is required so that it is not displayed as an input field
visible="0" "0" is required so that it is not displayed in the dialog
checkvar "1" optional - allows then to use variables as inline variables (with %$...% )
maxcount maximum number of runs
groups= $ROWCOUNT,$COLCOUNT optional to create a nesting of 2 groups
<title> </title> this text will be displayed in the fotoARRAY dialog, not required for loop variables
<title lang="German"> </title> This text will be displayed in the fotoARRAY dialog if the language is set to "German".
<default encode="0">....</default> The contents of the loop, with inline variables.
<start>....</start> Output before the loop.
<next>....</next> Output between passes.
<end>....</end> Output after the loop.
In case groups=... was used, start/next/end is ignored and these elements are used instead. The number of the group (0...) is specified explicitly.
This example produces output grouped by year.
It uses the variables ROWCOUNT and COLCOUNT as well as BGCOLOR which must also be defined in theme.xml.
The content of <default> is critically dependent on the StyleSheet used for the template.
In any case the characters < and > must be coded as $lt; and >. Images are included via %IMG% etc. as described.
