Feature request - Search by image name

[idoadse]

In some use cases, I encounter issues with specific images in the post processing of the results (not related to ddg but rather to the tagging process).

In these cases I would like to be able to insert the image name in a text box (in the summary pane), a regex filter will be applied on all images names (e.g. all that fulfil the predicate filter_text like image_name) will remain in the viewer.

This would be a nice addition and would go well with request #5 . Will probably be able to add this sooner than later.
