Thumbnail created whenever you add pictures or videos on your android. Thumbnails remains in your phone even after you delete pictures or videos from your android. Android don't delete these thumbnail files after restart.

If you hard reset then thumbnails get erased because it stored in internal storage as internal storage get erased.
Thumbnails created for all pics and videos. It doesn't matter it source.

Where is the thumbnail folder created if the camera pictures are stored in external memory card. Does thumbnail folder get created in external memory card or internal memory?

Vegan Gallery

My gallery is not scanning my gtab for pictures. I have pictures in a subfolder in the DCIM but it is not being recognized. Pictures taken by the camera are. They are all on the internal card. I tried clearing data and rebooting, but nothing. All of the pictures can be opened up via a file explorer.
How do I fix this?

Have yet to have this problem with my GTAB but when it happened with my N1 I deleted the cache folder for the Gallery:
Android/Data/Com.Cooliris.Media/Cache
Then Rebooted, this forced the OS to rebuild the Gallery thumbnails.
I'm not sure this is a good fix though.
Throw this in there, look up JustPictures!. I never liked the included galleries on any of my android devices.

[Q] Help! Duplicated photos in gallery

Hey developers, hi!!!
Always when I uploading or sending photos (via outlook or facebook), these photos appear two times in gallery.
Physically there aren't duplicated photos, it only happens in gallery app.
I've cleaned Sdcard cache, unmount sdcard, reboot phone, cleaned /cache and dalvik cache but these methods has no effect!!!
I hope that you help me, hahahahaha, it's a little ridiculous but it's really.
Thanks!!!!
Hi developers.... The solution to what I follow is to move the 100media folder to another folder (like downloads) , then refresh the gallery app....
Finally return the 100media folder to its dcim folder and refresh again the gallery app...
A simple solution heheheeheheh..... Cheers

What media? The backup files include only the chat conversations. Media files like videos, pictures and so on are stored in separate folders in the WhatsApp folder. Have a look at it on your phone.

Those type of media (pictures, videos etc.) are not part of the backup. You can manually back up those files by copying the folders Whatsapp Images, Whatsapp Videos etc. (which are inside of the Whatsapp folder on your internal storage) to an external storage, for example your external SD card. If you want to restore those files, simply copy them back into your Whatsapp folder.

Question GOOGLE PHOTOS

When I check the google photos app under photo settings/ back up & sync/ /back up device folders I don't see all the albums in my S22 gallery. Is anyone else having this problem?

That's known problem that users have with Google photos. I've looked into this on other forums. Google is not looking into fixing this any time soon.
I've tried multiple things but they really don't apply to what we are trying to do. For example i have a DJI (DRONE) folder that i want to back up but it's not even an option to select.
The only fix was to create a new folder in your "pictures" folder using a file explorer, and then transfer the pictures you want back up into that folder. Google photos will read the folders that are inside your "pictures" folder. You should now be able to backup that newly created folder. Hope that helps
I also wish there was a way to remove screenshots to be automatically backed up, unfortunately with Google photos there is no option to deselect the screenshot folder. Google photos is awesome in so many ways but these quirks are very annoying

Not sure what you mean, but Photos does detect images in the screenshots folder.
maybe the 100GB one drive offer is better than. anyone know if it syncs perfectly??
The problem is with Samsung phones. On previous phone Huawei, I didn't had this issue. Because in DCIM folder were only photos that I took. Everything else were in Pictures folder.
This is really annoying!

I use OneDrive and it works for me. It can be a bit confusing though so this explanation of how it works for me unfortunately must be a bit long. I do backup all except one or two folders on my computer to OneDrive. I don't remember the settings I might have initially put on OneDrive but here is what happens with my photos.
When I take a photo on my phone or do a screen capture on the phone, OD immediately uploads those to the cloud and then downloads them into a folder I have on my computer called "Camera Roll". So, within a few seconds to a minute of taking a photo or screenshot on my phone, those are available on my computer in the Camera Roll folder. Oddly when I then look at my pictures in OD, the photo will be saved there, but the screenshot will not. So even though OD syncs screenshots from my phone up to the cloud and then down to my Camera Roll folder on my computer, OD does not seem to save the screenshots in the cloud storage. But I end up with screenshots both on my phone and on my computer, so this is OK for me.
When someone sends me a photo in a message or email, those seem to get backed up by OD also. If I click the OD option to show photos from all folders, I do see those photos that were sent to me. I do get messages and emails both on my phone and on my computer, so I am not sure if it matters to OD if I first look at a photo received in a message on my computer or on my phone.
Once a photo is on my computer, if I edit it and save it to another folder on the computer, that copy will be backed up by OD also.
It gets interesting when deleting photos.
If I delete a photo from the Camera Roll folder on my computer, it is deleted from OD cloud storage also, but it is left in my gallery app on my phone. Of course, if I open OD on my phone and look, the photo is not there as it has been deleted from cloud storage.
If I delete a photo from my gallery app on my phone, as long as this photo has already been uploaded by OD, the only place it is deleted is on my phone. I like this because I can delete photos off my phone, but they stay in OD cloud storage and in my Camera Roll folder on my computer.
If I delete a photo in OD that has been previously uploaded from my phone’s camera and put into my computer’s Camera Roll folder, it is removed from OD and from the computer’s Camera Roll folder. It is left in my phone's gallery app though.
Hope this helps.

this is what i was worried about. i am trying to find an auto backup strategy where it backs it up maybe weekly. i take a lot of photos and that means i also sift through and delete many so syncing cloud and pc would be a headache. i have my phone san-photos/video already auto backed up to my samsung cloud so i'm just looking for a media sync that works for my needs. thanks for sharing.

Yes, because all photos taken get uploaded right away, and deleting a photo from the camera app does not delete it from OD, you end up with a lot of photos saved in OD that you don't really want. So yes, if you take hundreds of photos, this would be a pain. I am not sure of all the settings in OD though. Maybe you can have it backup only periodically or set it so a photo deleted on the phone also gets deleted from OD?
If I take a photo, it's not uploaded till I open photos: is this normal?

I am using OneDrive and immediately after I take a photo, that photo is uploaded to OD and downloaded to the Camera Roll folder on my Windows computer.
If I take photos on a hike in the woods and have no service, as soon as I get reconnected to cell service or wifi, the photos are uploaded.

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)
