[Q] saving contact photo taken when editing the contact profile

Is there anyway that i can extract/save the contact photo which i took using the phone camera while editing the contact profile?
I can't find the photo in the camera roll.
Understand that if i do a hard reset, the contact photo will be re-sync to my phone. Hence there must be a copy of it somewhere. Either in the cloud or my computer.
Where and how can i access and save this photo?

[Q] App that duplicates camera photo and puts to other folder

Is there an app that when you take a photo via camera, saves duplicate of this photo to any other map on the phone? For example if you take a photo of police officer, and he requests from you to delete the photo from main photos folder, but you still keep duplicate somewhere else?

Mass rename of local photos in Google Photos

I need to organise my photos. The way my camera app works is that it just uses the next available number (e.g. photo0001 photo0002 photo0003, etc) and just remembers the next number to use.
The issue with this is when you go back and delete photos, it leaves a blank "slot" (e.g. photo0008 photo0010 photo0011 photo0015, photos 9, 12, 13, and 14 were deleted), and if you ever reset your phone, the camera forgets and starts over from 0001, sees that number is already taken, and uses the next available number.
This results in your photos being in the correct order if you go by date taken, but a complete mess up you go by filename. I plan to fix this by using a mass-renamer that will rename them in order of date taken.
Issue with that is, I have no idea how Google Photos will handle this. It's suddenly going to see thousands of photos that are different from the version stored online (because their filenames now are different) and bundled of new photos which didn't exist before because they are existing photos that had their filename changed to one that wasn't in use before.
Will Google Photos be able to tell by performing some sort of visual check or using some sort of hash/checksum? Or is it just going to turn my album into a mess? What would be the best way to deal with this? I could turn off photo syncing, delete everything saved online, then re-enable it after I rename them, but that would mean I would have to re-upload all my photos and videos, my 64gb card is almost full and I am upgrading to 128, that would be a LOT of data to re-upload.

Question Date/Time Stamp Photos

Does any one know how to print the Date/Time Stamp on the photos by default? I know the workaround of opening each pic, and then adding a sticker but its a time consuming thing.
Can this be done by default with out a 3rd party app support?
Thanks
Um... the exif data should have that already and is automatically attached to the jpeg.
Android photo apps tend to have very poor exif management though. Canon apps are much better and easier to use.

MIUI Gallery reverse engineered

In the MIUI Gallery app data we have a picture database /data/user/0/com.miui.gallery/databases/gallery.db containing information such as timestamp, exif data and file name.
There is a cache directory /mnt/runtime/write/emulated/0/Android/data/com.miui.gallery/files/gallery_disk_cache/full_size containing thumbnails in 1080x1440 resolution.
How does the MIUI Gallery app know which preview belongs to which picture?
I am looking for information about the missing link. I have attached example app data for one picture. The original example picture is included.
The goal is to recover metadata of pictures. I lost the phone and MicroSD Card so the original photos are lost. But I have a f2fs disk dump of userdata partition, that allowed my to restore at least thumbnails of lost pictures. The goal is to find the link to the database entries, so I can at least restore the timestamp and file names.
My first attempt was to simply rename the files by mtime (see shell script) but unfortunately that doesn't reflect the correct timestamp, because that is only the creation date of the thumbnail (when first opened a picture in gallery)
