Visibility of TIF images in a family

[cbalestreri]

We have TIF images of principle's signatures we used to turn on and off in cad. In setting up the title block families, I can create a parameter that allows me to turn on and off the line work for the stamp, but not the TIF image of the signature. Is there a better way?

Why you cannot turn TIF off? I've already tested using visibility states in dynamic blocks and it works.

You can put signatures on designated layer and turn on/off it instead of using parameters (even if the signature is in block).

You have to add the TIFF images to a Generic Annotation family, and then nest that family into your Ttileblock.
For some reason, you can add parameters to GA families, but not to images
