No loading message

Hi, thansk for your answer. I prefer you to check url directly :
http://www.exnihilo-creations.com/main/stands-decors-communication-evenementielle/realisation-stands/

To resume, the page loads and the portfolio content is blank too long, waiting for (i think) all the pictures to load. I added in the code a simple “chargement en cours” waiting message but it’s not the best solution.

Is there a loading spinner or something normaly shown when portfolio loads with your plugin ?

Thanks
