Hi,
I think the fix suggestion in that thread would apply also for Masonry
me and others are putting together a new version of the plugin that is much more polished, has a better UI, more extendibility, it will be ready in a matter of just few weeks really
but I’m not sure if the imagesLoaded compatibility can be addressed, because of the reasons mentioned in that link in my last reply
you could tell your developer to add this to the theme:
https://qtip2.com/guides#integration.isotope – add imagesLoaded at the very end of the scripts and after masonry/isotope (these libraries seem to depend on imagesLoaded) and see if it works (if you do that, whether it works or not, some feedback would be mostly welcome)
perhaps I could make an add on for the future plugin that tries to add this fix to themes and loads imagesLoaded later, but I need to figure out how it would work and test it with a few themes/plugins combinations first, so I need a bit of time
