EXPAND thumbnail to full-size picture
The syntax is as follows:

folder,file_hint,max,show_filename,random,max_size

ex: expand('splashes_800','*',12,0,1,0);
folder is a valid location: splashes_800, stockpics, gallery1, etc...
file_hint is either '*' meaning search all files, or part of a file name (like 'venice')
max is the maximum number of thumbs to display
show_filename is either 1 or 0 (yes or no)
random is 0 to 4 : 0 as found, 1 random, 2 alpga up, 3 alpha down, 4 latest first
max_size is either 0 (full size) or an integer (ex: 600)

expand('splashes_800','*',12,0,4,0); (latest pics first, all same size)



expand('stockpics','ma',9,1,1,0); (random, show filename, variable size pics)


expand('stockpics','*',9,0,1,600); (random, variable size pics, expand to 600 max)
