Some help needed - pasting screenshots together

    First off let me say I'm completely new to this, and am hoping someone can help me out.
    I'm using GIMP, and want to paste a number of screenshots together to form one huge picture.
    I'm taking screenshots from the map of Ireland here:

    and am trying to paste them together to make a giant map of Ireland to transfer to my PDA.
    First problem is that I don't know how to set the picture size. I wonder could someone give me some help on how to do this?

    Work at the pixel resolution of the originals and stitch them together in small groups, e.g. 4 x 4 squares or strips of 10 that are easy to handle, then stitch them together. Try to get enough overlap to lose the logo when you paste the top of one image over the bottom of the one above, and keep the spacing and image size the same for each screen - Gimp will show the exact pixel positions as you paste the image. In a 4 x 4 you could use four layers with the top row of images in the bottom layer, then the second, third and bottom row.

    I made a big satellite photo and did it the complicated way - I started at my home and saved jpeg images 00-00.jpg, 00-01.jpg (one move) right, 01-03.jpg (one down, one right), etc. I measured the pixel overlap, the remaining pixel size and the size in pixels of the whole image. Then I pasted them together knowing the final size using a program written R (http://cran.r-project.org/), but it was overkill.

    Hugin (http://hugin.sourceforge.net/) is much easier and if it was real photographs you might like (http://panotools.sourceforge.net/) to automatically align images in a set, but that won't be necessary with precise horizontals and verticals. Rows or columns of 10 images would probably be manageable, but there is nothing to stop you trying a 10 x 10 if you have the patience to organise the 100 source files.
