You will need to upload the image to Joe Bonamassa to get it to appear on his page.
We had Split Releases before and Kode added the script to have it appear on both
I'll have to check with him to see what the script does. There is an entry for "Live in Amsterdam" on Joe Bonamassa's page, but obviously no image. I have uploaded several split release over the last few months, and have had to upload the image to both artists for it to actually appear on both pages.
