How to include .tiff files for visual markup

Hello, I've tested this using the OOTB Express ECO and Simple ECO ItemTypes, and I can confirm that the .tiff image is able to viewed after a Document is added as an affected item. One thing to note here is that the files to be displayed in this relationship are being pulled from the Affected Items. Because of this, the FileSelectorTemplate of the child ItemType must be changed rather than the FileSelectorTemplate of the Express ECO or Simple ECO. Could you please confirm that you have updated the FileSelectorTemplate of the ItemType you are adding as an Affected Item rather than your Custom Item Type? Additionally, if you are still having this issue, could you please provide the code that runs in your custom "get my affected control items" method?
