Do you have some examples of strings you want to validate?
Is it just a filename with an extension?

i want to validate only image files.

It would be easier to check server side if PhotoUpload1.HasFile then GetFileExtension (or some such) - provide extension list and check.

What about tif, tiff and png files? Those are image files too.
