Normally, the format is something as this: "YYMMDD_hhmmss.jpg"
The new change attributes with plugins don't let you use filenames as input data, only plugins of dates or times are allowed.
This could be done with a new plugin.
Should be configurable, in this case could be something like [plugin.0YYMMDD] for the writedate plugin and [plugin.7hhmmss] for the writetime plugin.
The first number defines the offset and the following characters the format.
What do you guys think?. Maybe Hacker read this post and he likes the idea.
