Step 1:
Download Xnview for your platform.
Step 2:
Collect all the images you need into a directory. I am using 30 random images from a recent trek each of size 3008x2000 as an example.
Step 3:
Open XnView and browse to the directory containing the images.
Optional : Resize the images using "Tools->Sequence Convert" to the size/ratio you want or crop the images. A 20" by 30" print may require a 3:2 ratio. This can be done later also on the final image(which is what I did).
Step 4:
Select all the images and click on the "Tools->Create Contact Sheet". Time to do some math...and select the parameters you need.
This is the setup I used:

I have divided the 30 images into 6 columns and 5 rows. Considering my individual image size as 3000x2000, this results in a combined image of approximately 18000x10000. I have chosen half that(one fourth if you think about it) and hence set the final image size to 9000x5000. Filenames, headers, footers are all your choice but I have not selected any of those options.
Click on the "Create" button and wait for XnView to do the magic. With some luck on the parameters, you should get an image properly aligned.
Step 5:
Optional : Resize the image to your desired ratio(eg 3:2).
Save the resulting image in the TIFF format and you are ready to go.
My sample TIFF was 131 MB in size:

"Error: Can't allocate memory for result image(s) !
Out of memory".
That is when I tried XnView which did not seem to have this problem even for a bigger image.

Margins between pix
I'm not sure why mine keeps coming out with gaps between pictures.The result that you show makes that gap very narrow. How can I adjust that?
Thanks!

Re: Margins between pix
You need to resize the images to get them in the same size/ratio.Also, when setting the final image size, you need to consider the size of the individual images and the number of rows and columns. In my example:
3000x2000 images arranged into a 6x5 tile gives a total image size of 18000x10000 with a perfect fit. I have taken 1/2 of this to get 9000x5000. Once you get this tightly fit image, you can resize it to the size of the print you need.

Re: Margins between pix
I went ahead and tried Picasa2 (I didn't like the original) and used the Collage function - chose GRID, and viola! I have a Life Poster without having to calculate any math or ratios. It does it for me.Try it out!

Re: Margins between pix
I guess it is a question of flexibility. I too had tried Picasa2 but it produces a square image(with square pictures) without giving me the options to customize anything at all and it also gave a smaller image when I needed something for a 20"x30" print.July 16 2008, 04:59:36 UTC 3 years ago

photo collage
Doing it in columns does not look great or nice. It should look natural, not in a controlled force pattern or form, it must at the end of the job look like one big picture/photo. I da seen it at kodak, very nice that way.Anyone can do it this way, even on MS Word, just paste all photos on 1 sheet and resize.

Happy 1 Year Birthday Life Poster
I wrote an article about Life Poster's 1 year birthday (http://www.dkworldwide.com/techlife/archives/2006/01/01/life-poster-a-picasa-how-to/trackback/) for my blog which references your work with XnView. I wrote a how-to on making a LifePoster with Picasa. My blog is also published in a newspaper so maybe the less tech savvy can benefit from your great work.Anonymous

nothing happens
nothing happens after i hit Create in "Tools->Create Contact Sheet"...what could i have done wrong? what does the contact sheet look like, in the browser or somewhere else?February 26 2007, 06:10:50 UTC 5 years ago
Re: nothing happens
Check if you have selected the images you want; it usually takes some time to create the final image which opens up automatically once the process is complete.Anonymous

file names
Hi, when I create the collage, the photo file names are showing up underneath the photos. Do you know how I can get rid of them?Thanks!
February 27 2007, 04:23:02 UTC 5 years ago
Re: file names
just un-select the Header, Footer and Show Info options in the Create Contact Sheet dialog.Anonymous

Another method
I wrote a little script that does this - all you need to do is tell it how many pictures across and how many down you want and point it to a folder of photos. Job done. You can get it here: http://wiki.edsimpson.co.uk/index.php/MaThere are of course many built-in parameters that can be easily edited, such as poster size, margins, etc.

Works like a charm
Thanks buddy - it works brilliantly and overall the software lets you do so many other things as well. Great find!!!The key is to make sure that the resizing of images is done and you do the math to figure out what the final size of image is with borders/margins -
I had a 15x15 (225) image collage - i changed all the images to 640x480 - gave a 100 pixel margin. So my resulting image size was 15*640+100 X 15*480+100
It was a 14MB jpg as a result of this...
