What is your ssu version? I know for certain if SSU is installed correctly, it does not interfere with anything on the admin side (since it is not supposed to rewrite anything there)
Also, knowing how IH2 works, I doubt that SSU can interfere with this in any way.

But just to make sure, disable SSU, then upload additional images, and see if those new added images work.

If they do, then SSU is at fault, which is weird btw, you may check if you uploaded files to the wrong folder. Anyhow, in that case, you can try to upgrade to latest version which is 3.6.4, then try adding new images again and see if they appear.
