Using native FileMaker tools to do this, it might be done, but it wouldn't be easy. Basically, you'd have to overlay the container field with a grid of transparent buttons, each with a tooltip that would function as a calculation. Clicking a button, (they could be popovers) could run a script that opens a dialog for the user to enter information that is then referenced by the tool tip. Getting the right button size would not be easy. The tool tips, come to think of it, wouldn't work on iOS devices anyway. You'd have to set up either massive numbers of fields with visibility controlled by "hide object when" or something to show the "tags" all at the same time without relying on a mouse hover to open the info.
I've done something similar to that before and it worked, but in that case we had control of the image size and it was for a very limited number of images.
My concern for this project is that there will be users in the field importing the photos, so I have no real control of the photo size unless I was to build some type of control script that might adjust the photos to a standard size upon import or keeps the original photos but resizes a copy for a specific container to display with the grid on top.
But all that adds complications to the project and I'm really wanting to keep this as simple as possible.
Taylor - I was hoping it was going to be easy -_-
I've never been a JS programmer, but have a good friend that loves it / swears by it / swears at it.
I might have to bring him into this project :-)
Appreciate the response
