I was looking for a plugin with a friendly UI so that the client can upload images herself, placing images in a variety of categories, that then outputs like isotape. I don’t think this is possible with just using isotope, as the client will not have control.
I was after a plug-in that allows the client to upload images in the wordpress admin. The client can upload images to specific categories. Once uploaded, the output on the webpage is similar to isotape, allowing the user to navigate the categories, where the content smoothly reshuffles to show the selected category content.
