I guess what I am looking for is probably the holy grail. I would just like to leave my monitor setting alone and be able to go from post to post and forum to forum and be able to have the text large enough to read and the photo's all on the page to see without having to change settings. I don't want to have to zoom every photo to see it at a reasonable size. By the same token I don't want to have to shrink a photo just so it will fit the monitor. I would also like what works for me in this respect to work for you and everyone else even though we all have different equipment. This may be wishful thinking but I keep hoping.
I have found a couple of things that might work but am still looking. I will share them with you and Eric via PM when I get them all together.
I think you're right, at the moment that's wishful thinking

However, it needn't be: Your browser has already told the webserver how big its screen is (indeed, it's even told it how big the window is that the browser is running in), so there's no reason why a plugin couldn't take that information, and size a photo accordingly. This would be harder for in-line photos (but not impossible), where it would get as good as impossible is when you get into tables. I don't know if SMF uses HTML tables (a quick squint at the source of this page suggests not, but I didn't look very hard), if it does then we're back on a hiding to nothing; if not, well, who knows...
Unfortunately, I've got a seriously busy time at work just now, and as soon as I've scoffed me tea I'm down here at the workshop trying not to fry my shiny(ish) new(ish) cnc mill - hmm, if I plug them both in at the same time, I might be able to make them toast each other
