The Main menu of the application features nine options: File, Edit, View, Image, Brush, Colour Profile, Tools, Language and Help.
Under the Main menu there is the Taskbar of the editor. It has a number of buttons for the often used actions. One button deserves special attention - the button Tools. It opens up the Toolbar otherwise disabled. This button (the most right button in the Taskbar) has no associated tip; its designation is defined by a title. Other buttons have associated tips which are activated when a mouse cursor touches a button.
At the bottom of the Main window there are the status bar which indicates current position of the mouse pointer and color composition of the current pixel.
The option File starts File Dialog. Besides usual options of file opening/closing (Open, Save, Save As amd Close) it features options of creating a new image file New/Properties and New From Clipboard. They are rather peculiar and demand some explanation. The option New From Clipboard creates a new image if there is some image in the Clipboard - using the Clipboard image as a template. The option New/Properties has dual assignment: If there is no opened image in the workspace of the editor it creates a blank image. If there is some opened image in the workspace this option opens the Properties window of the current image.
The option Recent… is standard and maintains the list of recently opened image files.
The options Page Setup and Print must support printing but they are currently disabled. Working with the application I couldn’t enable them.
The option Edit opens Edit Dialog. This popup is rather short. It contains only options of undoing/redoing changes Undo and Redo, the checkable option of enabling/disabling the Undo function Enable Indo, discarding the Undo queue Discard Undo Queue, and options of copying the whole document either as a new image Copy Document or as a code sample Copy Document as Code. There are no standard options such as Cut, Copy, Paste etc.
The option Image calls the popup containing options of various effects you could apply to images. The option Brush serves, in essence, the same purpose; here you can copy to clipboard some other image and paste it into current image, rotate and flip the image. There is also the option Save As allowing to save the current sample to disk.
The option Colour Profile handles colour profiles of the application.
The option Tools handles registered in the application file types, allows colour testing and working with scripts.
The option Language opens a small language popup. Currently this popup has only two options - English (the basic language of the utility) and Afrikaans 
(rather exotic, eh?).
The option Help of the Main menu calls a popup with two options: Help and About. The application Help is in an .html form and rather short. There are no context-dependent help. Be cautious by choosing the Help option because it replaces the currently opened web-page in an Internet browser by its own .html page.
The option About initiates the About window containing some information about the application and contacts with the developer.
Some remarks about working within the application from the developer:
Tools generally use the current foreground colour on a left click and the background colour on a right click. The primitive tools can either be filled or outline. You can select which behaviour using the icon 
i.Mage has only one “document” open at a time. This document is a linear array of pixels of a given bit depth, either 8 bit indexed colour or 16/24/32 bit true colour. The same document is displayed in both the right and left panes at different zoom levels. The left pane shows the pixels zoomed to a specified level and the right pane shows pixel for pixel.
When you select part of an i.Mage it is copied into whats known as the “brush”. The brush is just another bitmap which attaches itself to the mouse cursor as it travels over the document. If you click while holding the brush over the document the brush is combined with the document using the current opererator. The brush is not the windows clipboard. Although it can be easily copyed and pasted to and from the clipboard.
Downloading of the application is available at the web-page http://www.memecode.com/image.php. Currently there are several versions of i.Mage for downloading - the newest version is 1.06.
The author honestly warns he hasn’t much time for work on the instrument so requests for bug fixing may take some time to get attention from him.
