You're right Chuck, you can't please everyone all the time - it's true.
As far as changing the icons to text links, on my gallery, I could only figure out how to change about half of them. I gather that's the way it works? Some appear as icons still, some change to text links?
And as far as the forum posting code, I think if it was an option, or changed, so that the code appeared so that you could link to the largest image that would be good. And also, having the posting code only appear when viewing certain size images gets confusing.
So here's what I suggest...
Below each image regardless of size....
