Is there anyway to get photos back on VSCO?

I had to delete all of my apps on my iPhone because of issues with my Apple ID, and when I logged into VSCO after redownloading it, all of the photos I had put on there to update and didn't post were gone. I probably have most of those photos in a drive or something but they won't be in as good quality most likely. Is there anyway to restore the photos or anything?

You are describing yet one more reason to save all your high resolution images as backup either on your computers hard drive or burn a CD/DVD/BD disc
