Hi. I have a listbox that I populate with say 100 images from a particular directory. I want to be able to select 7 of them, rotate them 90 degrees and then display next to each other in a subplot.
This is my code below for a single image selection, (note that the x position of the position vector for subplot requires the user to change a number in an edit box).
Thanks Jason
ListOfImageNames = get(handles.listbox1, 'string')
baseImageFileName = strcat(cell2mat(ListOfImageNames(Selected)));
fullImageFileName = [folder '\' baseImageFileName]; % Prepend folder.
figure(100);
file=fullImageFileName
IM = imread(file);
IM=imrotate(IM,angle);
subpos
x=0.101*(subpos-1)
positionVector = [0.0+x, 0.8, 0.1, 0.1];
subplot('Position',positionVector);
%subplot(4,7,subpos);
imagesc(IM,[0 5000])
colormap (gray);
axis off;
set(gca,'ytick',[]);
set(gca,'xtick',[]);

Change the max and min property of listbox. Refer this link : http://www.mathworks.in/help/matlab/ref/uicontrol_props.html#bqxoinq
If max-min >1, you can select multiple elements from listbox.

How do you then access those selected items? Thanks

Use ctrl or shift key to access multiple items. Listbox callback is executed at every mouse click or keypress, so you might have to associate a push button with it to direct a callback. See this prototype:
function pushbutton1_callback(hObject , eventdata , handles)
fileNames = get(handles.listbox1 , 'string')
ind = get(handles.listbox1 , 'value')
filesToAccess = fileNames(ind)
