This feature comes pre-enabled on all V3 Accessports. If the option does not appear, you may need to update the firmware on your Accessport or your version of Accessport Manager
Steps to Use:
Install Accessport Manager onto your computer.
Link your Accessport to you computer in Accessport Manager.
Drag any type of supported image into the file area of Accessport Manager (JPEG/JPG, BMP, GIF and PNG are all supported)
You can also press the "Import Image" button and select a file that way.
On the right hand side of Accessport Manager click the button that looks like a camera
Select which file you want to use.
Click "Yes" to import that image as the Accessport startup screen.
If the image size is not optimal you will see a popup message, you can either exit out and resize it, or click "OK" for it to be resized automatically.
In order to restore the default startup image delete "startup_screen.fb" file from the Accessport by highlighting it and then clicking the garbage can.
