How to call interface by clicking on the Image

If I click on Image it should redirect to an interface(form).

I have tried in the below way:

image:a!documentimage(document: documentid,

link:a!startprocesslink(processModel: cons!Processmodelname) /*In Processmodelname I have used a userinputtask & in that I have given my interface on form tab but it redirectng to Tempo>News*/

Please suggest.
