I have an image field type configured to accept an unlimited number of values.
Using the File (Field) Paths module I have set the file name field value to
This is fine if you upload one image because it is renamed to my_node_title.jpg for example.
If you upload several images, they are renamed to my_node_title.jpg, my_node_title_0.jpg, my_node_title_1.jpg, my_node_title_2.jpg and so on.
Is there a token I could use or create that would allow me to add a serial value rather than the default _0, _1, _2? For example my_node_title_a.jpg, my_node_title_b.jpg, my_node_title_c.jpg etc.
I'm looking at the Custom Tokens module at the moment but not having much success.
