Assuming this is for Squeak, here is how you can load the image
    instVar := Form fromFileNamed: 'myFile.jpeg'.

Assuming you are using the canvas api, here is how to display it, as gif :
    html image form: instVar.
as jpeg :
    html image form: instVar; mimeType: 'image/jpeg'.
as png :
    html image form: instVar; mimeType: 'image/png'.

You can optionally specify a file name
    html image form: instVar; mimeType: 'image/png'; fileName: 'foo.png'.

Enjoy,
Michel.

yes

I guess this would depend on the platform. On Windows, these would work
   Form fromFileNamed: 'c:\Graphics\myFile.jpeg'.
   Form fromFileNamed: '.\Graphics\myFile.jpeg'.

By default, you are using the "classic" api, but the recommended api is
the new
canvas api. To enable the canvas api, your component must implement this :
   rendererClass
         ^WARenderCanvas

Of course, you can also display images using the "classic" api,
something like
this should work :
   html imageWithDocument: instVar mimeType: 'image/jpeg' fileName:
'foo.jpeg'.

HTH
Michel.
