How to Organize Photos Like Slidebox in HashPhotos
In HashPhotos, you can quickly and conveniently sort photos into albums or delete them just like in the Slidebox app.
View Unsorted Photos - Unsorted Album
Tap Unsorted Album in the left sidebar to view photos that haven't been organized (not assigned to albums).
Album Bar
Using the Album Bar, you can easily and quickly assign photos to albums by simply tapping the desired album from the list at the bottom while viewing photos.
To show the album bar, tap the Add To button (or album title) in the top right of the viewer and tap Show Album Bar.
For more details about the Album Bar, please refer to the YouTube video.
HashPhotos provides several other features for organizing albums besides the Album Bar. Please refer to the guide.
Adding Photos to Tray for Deletion
In HashPhotos, you can use the Tray feature to collect photos you want to delete while viewing them, and then delete them all at once.
The Tray can be used for various purposes beyond deletion. (For more details, please refer to the YouTube video or guide.)
* The reason why it's better to delete photos by adding them to the Tray rather than deleting them immediately is that iOS always shows a confirm alert when deleting photos.
This means that you have to confirm each time you delete a photo, but if you add them to the Tray and delete them all at once, you only need to confirm once.
Delete Photos in the Tray
Tap the Tray button in the top right of the thumbnail screen to view photos collected in the Tray.
Tap the trash can button in the bottom toolbar of the Tray to delete all collected photos at once.
Adding Photos to Tray with Swipe Up Gesture
You can set the swipe up gesture to add photos to Tray in Settings > Viewer > Swipe Up Gesture Action.
