I can't seem to figure out how to display two images at the same time. I've read about subplots, figures, etc., but I just want to show two pictures side by side on the screen. Below is what I've tried with Psychtoolbox, but if you have any suggestions I would appreciate it!
win = Screen('OpenWindow',0); % Full sized screen
Screen('FillRect', win, black);
clear imagedata1;
clear imagedata2;
Screen('DrawTexture',win,TexturePointer1, 0);
Screen('DrawTexture',win,TexturePointer2, 0);

Sorry I did not say that but I have tried that too. I read in both images with imread. Then I resize them. Put them together with imshow(as you said). Then I make a texture of the concatenated image ( this is where the mistake probably is but I have not worked around yet :( ). and then i use Screen('DrawTexture'). If anyone knows where my mistake is I`d be truly happy.

Start your own question and be sure to post your two images.

Lots of ways
imshow([imagedata1, imagedata2]); % Assumes same number of rows in each.
Or you can use imshowpair() or imfuse().

what does (1,2,2) means ?

subplot() sets up a grid of "slots" where you can place a graph or image. The first number is the number of rows or images, the second number is the number of columns in the layout, and the third number is the plot number in natural left-to-right, top-to bottom manner. So if you wanted an array of 12 plots with 3 rows and 4 columns, it would be
subplot(3, 4, n);
where n is defined like in the 3,4 layout below
1 2 3 4
5 6 7 8
9 10 11 12
You can also combine numbers, so for example if you wanted one image to take up the whole 3rd row, you could do
subplot(3, 4, 9:12);
If you wanted a plot in the 4th column you'd do
subplot(3, 4, [4,8,12]);
plot(x, y);

Use imshowpair like Image Analyst suggests and you should be all fine.
The following gives you a side-by-side display:
imshowpair(im1, im2, 'montage')

How about if we want to show the image on top of each others instead of side by side?

imshowpair(imrotate(im1,90), imrotate(im2,90), 'montage');
set(gca,'view',[90 90])
