How to use slider bars to view images from a dataset?

Let's say I have loaded a dataset of 100 images and I want to view those images by scrolling the slide bar. If I set my slide bar to 25%( where min limit of slidebar is 0% and max limit is 100%) then 25 images out of 100 should be displayed likewise if I scroll my slidebar upto 89% then 89 images should be displayed. I tried implementing it by loading an array but it doesnt work.

With the slide-bar at 89% do you really want to simultaneously display 89 images? In one figure? (that would be a large number of subplots and very small images to look at...)

[Divya Priyadarshni]

I would half the ratio, if too small but yes it has to be simultaneous. I am implementing this in CBIR, so I just want the logic to work.

@Divya Are you looking for this slider window uislider or else?

No Kalyan, I am looking for the slider used here.

I didn't implement a case for the 0 position, so I just set the range limits from 1 to 100.

%Load an example image
a=imread('cameraman.tif');
%Replicate 100 times
database=repmat(a,1,1,100);
N_images=size(database,3);

%prepare figure and guidata struct
h=struct;
h.f=figure;
h.ax=axes('Parent',h.f,...
    'Units','Normalized',...
    'Position',[0.1 0.1 0.6 0.8]);
h.slider=uicontrol('Parent',h.f,...
    'Units','Normalized',...
    'Position',[0.8 0.1 0.1 0.8],...
    'Style','Slider',...
    'BackgroundColor',[1 1 1],...
    'Min',1,'Max',N_images,'Value',1,...
    'Callback',@sliderCallback);

%store image database to the guidata struct as well
h.database=database;
guidata(h.f,h)

%trigger a callback
sliderCallback(h.slider)

function sliderCallback(hObject,eventdata)
h=guidata(hObject);
count=round(get(hObject,'Value'));
IM=h.database(:,:,1:count);
IM=permute(IM,[1 2 4 3]);%montage needs the 3rd dim to be the color channel
montage(IM,'Parent',h.ax);
end

Perhaps have a look at: Imthumb, it might not be exactly what you want, but it might be close enough for you to easily modify...
