Hi Alain,

you string pattern is nuts.

""~~ .....

A string expression that starts with the empty string is superfluous.

ToString[NAME2]*".jpg"

* is the multiplication operator, hardly what you want.

What you want is e.g.:

ToString[NAME2]~~__~~".jpg"

This means: the string in NAME2, followed by any sequence of one or more 

characters, followed by ".jpg"
