I am making a Cartodb map that is supposed to show different pictures of a park in popups at points along a park path. I started by making a different layer for each point but by the time I created 4 layers it looked like it was going to stop allowing me to create any more. I have around 30 unique popups that I need to make. Is there a way to create multiple points in one layer and edit them each separately?
Depending on your account type, CARTO has a limit of layers that you can add per map. For example FREE accounts have 4 layers as a limit.
It is possible to edit the points of the layer and edit each point (each point/geometry is stored in the_geom column of the dataset) in the data view of the map or of the dataset that you are using to create the map.
If I understood you correctly (let me know if I'm wrong!) you want to add a different picture for each popup. You could add a column where each row of the column could contain a different URL (1 row = 1 geometry and its attributes) of each image on your dataset and then use the infowindow "image header" template to display the images in the popups.
