You have several problems; looking up the value in the XML file, and renaming the file.

To look up the number corresponding to Gallery2 or whatever, I would recommend having a look at StackOverflow question 1169398 which explains how to look up nodes/values in an XML file.

To rename a file in .NET, use something like this:

using System.IO;

FileInfo fi = new FileInfo("c:\\images\\gallery\\add.gif");
if (fi.Exists)
{
    fi.MoveTo("c:\\images\\gallery\\thumb3.gif");
}

Of course, you would use string variables instead of string literals for the paths.

That should give you enough information to piece it together and solve your particular lookup-rename problem.
