Only two merge layouts required, one is merging horizontally and another is merging vertically. 4. Maximum merge images should be only 2. 5. User can select images from the gallery, different folders as shown in picture-1. 6. Automatically the selected pictures should show in choose merge layouts. 7. If we click on the selected layout, it should go to the next page i.e selected layout in a bigger size. 8. Selected images can be adjusted with zoom in and zoom out with respective layouts and photos can be interchanged by simply dragging. 9. If the user proceeds to next, the selected layout should come in next page. Please refer to picture-2 and picture-3. 10. Please refer to Instagram layouts.
