SUMMARY
When using the Export > Export to Flickr... menu item, I am presented with a dialog box that seems to require me to select a file on the file system. I am unable to select a directory and can only select a single file. Select all and shift and cmd clicking don't select multiple files.

This is true if I use the + button or the file folder icon button.

I'd like to be able to sync and combination of selected tags, but I don't see any option for that. All export options (SmugMug etc) seem to present the same dialog, though with different login options.

This might be a wish list item, but I'd also like to not have to select anything off the filesystem, and use the Digikam standard interface to export any items in the current filter or by tag. Albums are insufficient for my needs. I love Digikam, but this is probably a deal breaker unless I roll some code to sync with Photos (which I might :-)).

STEPS TO REPRODUCE
1. Click the Export > Export to Flickr... menu item.
2. Select an account.
3. Click any button that prompts for files (+ or the file folder icon at the bottom).
4. Try to select a directory or more than one image.

OBSERVED RESULT
Only a single image is selectable.

EXPECTED RESULT
Any number of images should be able to opened/selected.
