I didnt understand what you were trying to achieve... but what I made out from the image above , i'll elaborate that. You Need to do the following :
- Install PhotoShop on your System or any other Image editing app
- Open a New File with the dimensions 11 x 8.5 Inches (1 Inch is 96 pixels / px)
- On the top of the page start with "introduction" and on the right side of intro place 1 image
- All the space below before it with images to make a collage
- You just have to drag and drop images inside the program and adjust them to make a collage.
- Once Done, just go to File > Export > Save .
- Hope this helps ?
