I would like to be able create a way to click on a photo and have it send a value to another server connect and open a modal with additional information about the photo and to show a larger version.

Is this possible to do?

You can use the data detail for this:

Also please consider switching to Wappler, as it offers more features than the DW extensions and generates up-to-date code.
