Recent pictures deleted after iPhone backup?

I backed up my iPhone in order to retrieve multiple notes that were deleted and in the process my most recent photos were deleted off of my phone. How would I place those pictures back on my phone without doing another backup?

You can't, sorry.
Next time transfer pictures and purchases first. Then restore.

Restore puts content, at the time of the last back up, back onto your device. But it also removes any content, changes or additions since the last back up.

Add Dropbox to your computer and iPod. It's free and will automatically download pics and video to your Dropbox. Notes and documents can also be stored in Dropbox. This makes them available from any device you sign in to that has Dropbox.
