Delete a presentation and upload it again just for remuve 1 image its a waste of time.

We need an option for delete 1 image and if this option exist say me were :S

I agree, finding that 1 photo hasn't synthed is just annoying.
Easily being able to delete a couple of photographs without loosing the synth would be a great feature.

As far as I know, changing anything in a synth demands that it be recalculated. You will not need to upload any new images (they're already on the server), so simply make the selection again, and set it off recalculating.

Simply removing an image would break all the links it has created across it's neighbouring photos. How does the one to the left now link to the one to the right of the removed image?

Of course I could be totally wrong...

I agree and get really pissy about it!

there could easily be a mute/rem/hide for the image, who cares if it's still there just don't show it or navigate to it!
