Hi Ernie and Anne, We ask people not to have spaces in their file names or other unusual punctuation symbols that unix may not recognize. The examples I used may have looked like there was a space since I used an underscore instead of the space and the whole name is automatically underlined by some email programs if they recognize a url so you couldn't tell. Genus_species.jpg and Habranthus_coeruleus.jpg were examples I used. So you are correct Ernie. Spaces shouldn't be used. If you use spaces there are often problems with people seeing your pictures and it makes work for me as I have to rename the file. Anne, I'll write your privately about how to use our wiki. Mary Sue
