You can embed link from Link panel: select the picture and choose Emed Link.
Another workaround you can package you document: Alt+Shift+Ctrl+P, that allow all links to go with you document.
Will both options still let me to open and edit with Photoshop?
If you embed the image you will need to unembed the image first to edit in photoshop.
It's best to use the link option and the packaging.
I have started to package my files to Dropbox where I have a folder on "MY Documents" called "Dropbox".
This is linked to a cloud storage service which will then upload my images to a cloud.
I open Dropbox on another computer and the files will sync automatically.
It's a very efficient way of transferring your files and keeping them all in the one location.
Package let you to edit with photoshop.
For embed link, first you want to unembed from link panel and after that edit with photoshop.
Be VERY careful here. If you are working with a linked image that is accessible to only one of the copies of the ID file the other copy will not show the updated image if you edit, and worse, it won't warn you that the link is out of date (becasue for that file it isn't).
If you need to actually edit both the .indd and the images on multiple machines you really need to store everything in one location that is accessible from anywhere.
