Uploading image

[gilis]

Thank you Michiel as well,
I stand corrected. I know how silly it sounded, but usually there is
some correlation between the image physical diamensions, size on disk
and its pixel -size.
Thanks alot for your advices in regard  to the use in in canvs.

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).
