Is full Option Set Downloaded on single item reference

Is complete option set downloaded even if one particular option set item is referenced?

I remember reading somewhere that whole option set is downloaded when we refer to an option set.

I can imagine it to be done in case we are doing something like all items in optlist: filtered but is it also true in case of single item reference?

I have an option set called “Images” where I put certain images which are used at different places in the app e.g. Brand logo etc.

Wondering if all those images are getting downloaded to the client side even if only one or few of the images are being used on the page.

All option sets are loaded on page load, without exception.

Your ‘images’ in the option set are actually URLs. This isn’t problematic as the images will only be downloaded from the URL when necessary.

Thanks. This helps.

It is odd that all option sets are loaded on every page load even if they are not used on that page.
