in a RegularExpressionValidator. The only problem was with the string
case. I didn't find a way to specify that the regular expression is case
insensitive for the RegularExpressionValidator. The expression can be
rewritten to
^.+\.(([jJ][pP][eE]?[gG])|([gG][iI][fF]))$
to allow extensions like jPeG etc
