I have a script on my site which lets people upload files into an image gallery. Unfortunately, some people are uploading files with names like "me~swimming.jpg" and "J.R,ewing.jpg"

I tried to sort this by using this snippet: 

$imagename =~ s/\W/\_/g;

[download]
But this gives me "me_swimming_jpg" and "J_R_ewing_jpg"

What's the best way to take out the non-alphanumeric symbols from the file name, but leave the .jpg extension intact?
