Hello Avishek, images will usually get to their relative position on leaderboards after first 50 or so duels. So an image that already had 130 duels, and is not in top 10% (above 615 score) will rarely get more duels. Since your image still has 20 duels left, it will gain it eventually without being paused. It can take, days or weeks, depending on the score of image and number of other images, but your image will get additional guaranteed duels.
I have two images that are currently in place for the top ten in animals for the week. Both were uploaded early on September 9th, three days ago. Neither one has 75 duels yet. At this rate, they won't hit 100 for another three to four days. Voting for the daily duels is horrendous. Too many votes are going to community duels at the cost of delaying daily duels for days on end... even for the highest rated images! Changes to the system are desperately needed. Scott, please do something!!!!
