Hello Francisco,


The Data Type that you should use to handle images is Binary Data.

About your second question, you should compare with the Built-in Function NullBinary().


An If condition should be something like this:


Hope that this helps you!

Francisco,

As Rui pointed, the type is Bynary Data and you should use the NullBinary() funciton do compare it.


Also,

You can check all "Null Types" clicking in the arrow next to null button in your expression editor window to see which option is the best for your situation (In case you don't know it):


Nice to note that some other function are also available via Binary Extension, but you have to add manually as a dependency:


With these functions you can enhance even more your validations if needed.


Cheers,
