This article describes how to delete photos from the app
You can only attach and delete photos from the mobile device.
Here's how on the app:
1. Login to the app
2. From the app, create and save your invoice
3. Tap on Invoice List
4. Select the invoice you would like to delete the photos from
5. An action bar slides out from the right -- that is how you know you are on the right screen at the bottom of this screen there is a camera icon
Tap on the camera icon
6. Tap the photo to edit
7. Tap the trash icon to delete the photo
If you have not previously given InvoiceASAP permission to access your photos, it will ask for permission.
If you have previously denied permission, then all you will see is a black screen.
If you have the black screen, then you will have to change the permission settings on the mobile settings.
Photos are not stored in high resolution, because it takes too much time to upload them.
