Just had a look in my database.... of the 27148 images....

2882 images have ( or ) in the file name
938 images have & in the file name
71 have [ or ] in the file name
4 have @ in the file name
5 have # in the file name
158 have + in the file name
4 have = in the file name
1 has $ in the file name
I can't solve this manually...
