    Email it to yourself - it'll be automatically resized!
    Can you R click on the jpg where you've got it filed? does that give an option like 'Open in' another program (Photo Editor in Windows) that will do resizing?
    Download excellent Paint.net - that'll do it too. If you SaveAs jpg it allows to to specify the %age compression which determines file size, and will convert many file formats, like big fat png to compressed jpg.

    My house has a portal timber I-beam frame built from Steico I-beams. As far as I can remember the important factors are the roof angle and what the I-beams are made of. The roof angle should be near 45 degrees, mine is 42 degrees. Some I-beams use OSB as the web material and others compressed board. I'm not sure about your case when joining the rafters to the walls, but the picture shows how mine is constructed.

    Edit:- The external racking is a big factor of course!
