About being able to set only one placeholder icon

Hello! I understand that you’re facing an issue currently. It seems that when you create a DMG file, sometimes there are two installation files. However, when you try to add both of them together, only one is displayed. Is it impossible to package both of them together into the DMG file? Also, the icon you selected for “add icon…” doesn’t appear.

To have both installation files copied to the DMG file, put them both in the source folder that you drag onto DropDMG to create the disk image.

The mounted disk image always displays all of the files. To control where it displays each icon, you need to add the icon to your layout. After clicking Add Icon…, you need to select a file with the same name as the one that you want to be positioned in the disk image’s window.

Thank you very much for your answer. I have already solved the problem. Wish you a pleasant life!
