I like the plasma dashboard, and I have started using the picture frame to for slideshows. The only problem is the positioning of the frame. It seems to be positioning from the top left of the image, which means if i have a landscape photo where i want it, when it switches to a portrait photo it looks out of place or goes off screen and vice versa if i position it from a portrait image initially. A simple solution would be for the widget to take its position from the centre of the image. would this be possible and if so how would i do it?

There is currently a patch on the Plasma reviewboard for this. You can monitor the review here

Once a plasma developer has set the status to "ship it", it will be committed to SVN Trunk.

Also, in 4.2 it will be automatically pulled back if it goes out of the screen.

In the Picture Frame Plasma widget / plasmoid, there is an option in the "Slideshow" section to

Change images every: hhmmss

Is there (or can there be) a similar option for the "Picture of the day" section?

(I know that this can be done with the plasma-widget-flickr widget, but that widget does not have all the options of the Picture Frame widget.)

The same question applies to the "Picture of the Day" Wallpaper changer in the Desktop Settings.

As they use different underlying code, this option will need to be implemented separately i'm afraid. I would suggest filing a feature request at bugs.kde.org. For a picture of the day however, it seems a little counter-intuitive to update more than once a day though.

Yeah, I put a wish request through on KDE bugs. I realise that the potd module is separate from the frame module, but since both are incorporated into the Picture Frame widget, I thought maybe it would be easy to port code from one module to the next.

Yeah, it's called Picture of the Day, but that's a colloquialism. The Flickr collection actually is called "Interesting Photos" and the other collections are not daily pics, either, and have a huge amount of photos.

(The original National Geographic Picture of the Day was added one pic per day, but the collection is huge and can all be accessed at once.)

I also realise that the plasma-widget-flickr allows timed slideshow access of their Interesting Photos, but that widget is only for Flickr, not the other collections included in the Picture Frame potd module.
