I don't understand this.
Here's what I want: Thumbnails in gallery at 250px. Thumbnails in Featured Photos block at 125px.
I fail to see what is so hard to understand here.
Like I said many times over the years you can code anything up you wish to be non standard from our default released code. Your the king of hacking you did not upgrade for years because you had hacked an old PhotoPost to death and refused to upgrade and still tried to come here for issues you had. You know we do not assist you with creating hacks and we do not support them.
Like I said you can try reapplying what is in post 12. What is posted in post 12 does exactly what you want but I offer no support or further advise on this issue.
