Hello and welcome to the forum!
I'd suggest some clarification, e.g. 'what is the 'original album', i.e. your 'Camera Roll', one created in the 'Photo App', or one sync from your computer - really makes a difference. Images in the 'Camera Roll' can be deleted via the iPad, however, if you have copied one or more into another folder created via the app, then only a 'link' is setup between the two images (the photo is NOT duplicated, just saves memory) - a single photo is easily deleted if it only represents a 'link' - however, if you delete the photo from the camera roll, the link(s) to this image in another folder(s) will also disappear; also, 'links' in created folders can be deleted individually.
Now this does not address photos that you have sync from the computer - please let us know if the above helps w/ your issue or whether you are attempting another maneuver - good luck!
P.S. sorry
