Photo editing app on ipad2

Question

I have an ongoing - time consuming - photo project requiring a lot of simple editing of photos - cropping, straightening etc and would like to be able to carry this out on my ipad2 when I am away without my MacBook.  My photos are all on my Mac and synced to the ipad through itunes rather than photos taken with the ipad camera itself.
I have downloaded Photo Shop Express App for ipad2 which is so simple and ideal for my needs and I have cropped etc a bunch of photos.
I now realise, and read on the Apple Support site,  that you cannot sync PS Express through itunes, so I cannot transfer the photos edited on my ipad back to my MacBook ----- unless someone can tell me how to do so??
Is there a way of syncing back or do you know of a simple editing App that will allow me to sync through itunes please?
Would be grateful for any help.

Answer 1

I think you are getting a little crossed.
once you edit the photo, its edited, and when you save it saves the edit as a seperate copy leaving the origional.
when you sync your iPad with your computer you will have your edited pictures.
(you are not syncing PS Express but the photos, which are and can be synced.)
if you have been doing editing, when you save you should see the copies you saved when you goto the next photo.
