The PRO version of the plugin allows you to use normal images from your media library as interactive elements in the map.
You’ll find the ‘Image Markers’ tab when creating your map with all the options, very similar to the other marker options, but with some options specific to images.
You can either set a default image for all entries or use a custom one for each entry. In both cases the above options will display. You can select an image, specify it’s size and select the point to where the image will align, considering the coordinates used. Just like for the other marker types, you’ll be able to set a tooltip, click actions and other information.
The images can be transparent and with any size you want, but smaller images will work better.
