I think I recall someone saying it's better to rename the beginning of the file name rather than the end...

 

For example...if the name of the file is  "my_cool_image.jpg"

 

It's better to rename it "1_my_cool_image.jpg"... rather than "my_cool_image_1.jpg"

 

Just something I recall reading here once that might be helpful.
