Uploading image

[David McFarlane]

Gili,

Hmm, I don't think anyone mentioned the Stretch property of Image 
objects.  Setting Stretch to "Yes" will stretch or shrink images of any 
pixel dimensions to exactly fit the Image frame in E-Prime (I use this 
feature myself to animate some displays).  But you should still pay 
attention to what others have said about first trying to get the 
dimensions of your images to better match your screen dimensions.

Images, in particular bitmap images, do not have a size *other than pixel-size*. As such, an image of 100 x 100 pixels will inevitably take up 100/1024 x 100/768 space on your monitor, should your monitor be set to 1024 x 768, unless you stretch the image over a different number of pixels (which usually leads to quality degrading results).
