facebook group photos?

[cell_phones@rocketmail.com]

Does anyone know if there is an app or is it possible to edit a Facebook groups photos online? I am admin of the group and I want to edit (add captions) to some of the photos in a album but if I add an app it only gives me access to my personal pics. If I upload a new pic I loosed the original comments, likes etc.
Thank you so much for the quick response! All I have been doing now is going to the photos and either uploading an new one with caption (we are trying to reunite lost animals after the floods in Canada) as I have most of the originals as I designed the posters that are getting shared. So I add reunited and upload a new one. But then we have 2 photos of the animals there one with the original captions "I live in the area will keep an eye out" etc and likes and the one I upload. If we remove the original we loose the likes and some really nice comments. But then like i said we have 2 in the same album. https://www.facebook.com/CalgaryFloodLostFoundPets
