Inkscape

I downloaded all the photos I had and placed them onto my desktop so I knew where they were. I downloaded inkscape and opened it and uploaded each image . The two photos that include just the trunk without the ucard I made the same height and width it was the third photo with the ucard that was different. The two trunk photos were stacked ontop of each other and were to the right of the photo that included the ucard. I made the photo with lichens of varying sizes and the trunk image a by using the square box tool and put a textbox within the left corner. I highlighted the box and duplicated it two times but put the letters b and c for the next two. I put the letter b for photo of the trunk with lichens that were very small in size. I put letter c for the image other trunk and the ucard. I placed the letters in the left corners of each box. I exported the Figure onto my desktop and set the width to 1300 pixel.
