Help for Displayator and the Displayable Creator

What is a Displayable

A Displayable is a transformed copy of an image so that it can be seen in full resolution on an iPad, iPhone or iPod Touch. You can create this transformed copy with the free “Displayable Creator” application running on a computer.

Displayables allow you to view your images at their original resolution. They can be created from big, very big or super big images.

To create a Displayable, you need an image in the BMP, PNG, GIF or JPEG format (but not JPEG CMYK). You need to run the image through the free "Displayable Creator application, available at It is a Java application, so you need to have the Java runtime installed on your computer (version 1.5 or newer). If Java is not already installed on your computer, you can get it from

Here is how to create a Displayable:

The creator then automatically creates the Displayable. The new Displayable is then added to the Share Displayable list and is ready to be downloaded or saved.

On your computer, the Displayable creator only read your image and create the Displayable in a temporary file that will be erased when you quit the Displayable Creator.

To save the new Displayable, for later use, click on the Edit icon and then select the location in which you want to save it.

Provided the Sharing checkbox is tick and your computer is on a wifi network, once the Displayable is created, it is automatically available on your local Wifi network for Displayator-running devices.

Loading Displayables from the internet

The Displayator app is configured to handle links with the following prefixes:

displayator-image: for a single Displayable. example.

displayator-list: for a list of Displayables. example.

Tapping on links with the above prefix from within iOS will launch the Displayator and offer to download the linked Displayable(s).

The Displayator Creator can create a directory containing the displayables you want to share and a web page containing the links described above. Once you upload this directory and send a link to the web page to other Displayator users, they too can download those Displayables on their iPhone / iPad / iPod Touch.
