bug#61394: 30.0.50; [PATCH] Image-dired thumb name based on content

[Manuel Giraud]

Hi,

Here is a proposal for a modification of how image-dired generates thumb
names.  With this patch, a thumb name will depend on the content of the
associated image.

Pros:
        - the thumb name is unique even if the file is moved or renamed
        - you keep a centralized thumb directory
Cons:
        - none (as it fits my usage :-)
