Loop through images in GUI

I have a cell array of images I am trying to loop through in a GUI using a 'NEXT' button, with two images on the screen at the same time. I have 9 images, each three are a series, and I have 3 series', such that I want to view 1 and 2, and 2 and 3, but not 3 and 1, which would be next in the list. I am having trouble coding this, so any help would be very much appreciated!

function next_block_Callback(hObject, eventdata, handles)

handles.curr_im_fig = handles.curr_im_fig+1;

if mod(handles.curr_im_fig,(handles.maxblock))~=0

   p1 = handles.curr_im_fig;

   p2 = handles.curr_im_fig+1;

else
   p1 = handles.curr_im_fig +2;

   p2 = handles.curr_im_fig + 3;
end

imshow(handles.images_fig{handles.curr_im_fig},'parent',handles.axes1);

imshow(handles.images_fig{(handles.curr_im_fig)+1},'parent',handles.axes2);

guidata(hObject,handles)

You don't appear to be using your p1 and p2. I assume these should be in the imshow command instead of the handles.curr_im_fig stuff.

Unsure what is suppose to happen when transitioning 3->4, 6->7, and 9->1, but I'd do something like this

function next_block_Callback(hObject, eventdata, handles)

% if handles.curr_im_fig is 3,6, or 9
if mod(handles.curr_im_fig,3)==0
    if handles.curr_im_fig >= 9
        % Reset count to 0
        handles.curr_im_fig = 0;
    end
   p1 = handles.curr_im_fig + 1;
   p2 = handles.curr_im_fig + 2;
   
   handles.curr_im_fig = handles.curr_im_fig + 2;
else
   p1 = handles.curr_im_fig;
   p2 = handles.curr_im_fig + 1;
   
   handles.curr_im_fig = handles.curr_im_fig + 1;
end
imshow(handles.images_fig{p1},'parent',handles.axes1);
imshow(handles.images_fig{p2},'parent',handles.axes2);
guidata(hObject,handles)

I'll just caution that I haven't tested this.
