1. Find the row (i-th) with max total width

2. Sort the images, so that widest goes first and narrowest last.

3. Loop for all images in i-th starting from widest (image A):

4. For each other row (j-th):

5. Try to move image A to j-th row. That is, if TotalSize[j] + width[A] < TotalSize[i], move and stop. Improvement done.
