Images Sizes and Forms

Image Field Types
The following field types are decoded and encoded in Base64 format into forms and some maximum do apply.
When designing forms which require a number of camera images remember
Due to a database size restriction only a total of 8 of the above fields can be used on a single form.
If you require more than 8 you should add them in individual records within an attached subform.
Camera file sizes vary based on device.
When designing forms which require a large number of images you should remember that with more modern devices the image sizes can be completely different.
Issue arriving from large image submissions include
- Longer processing times
- Notification issues if attachments exceed 10MB
- Potential timeout issues with network services.
Below is a table of devices and the size of a single image. In this case the answerSpace's "Native Application" settings were set at default levels
- Native Application => Capture Quality = 60
- Native Application => Capture Scale = 100
- Native Application => Target Width = N/A
- Native Application => Target Height = N/A
- Native Application => AllowEdit = N/A
- Native Application =>SavetoPhotoAlum = N/A
