My website is based on images, so I added the shortcode in the image caption, like here : http://www.r-graph-gallery.com/all-graphs/
The problem is that an image can be displayed in several pages of the website! So when someone likes the image in page A, I would like it to be upvoted in page B !
I did several trys but it does not work yet : when I upvoted an image, ALL the images of the gallery have shown a +1 score….
I would really appreciate if someone knews what happens ! Thanks !
