Outside of the Gallery Forum where you can post photos at will, I've generally advised people to keep pictures to less than 500 pixels width and less than 50K file size.
One nice thing to do is to post a small, maybe 300 pixel wide version of your picture, and then give a link to the larger version for those with bigger pipes who would like to see it.
It's not just a matter or your pipe size either. You can be sitting on the end of an OC3 and it can still take forever to download a picture if the server that picture is on is overloaded or if there's congestion on the network somewhere. And why would there be congestion on the network or an overloaded server? Maybe because 10,000 bladeforum members are trying to download some huge picture. So, it's just good internet etiquette in general to post a small picture and then a link to a large picture for folks that really want to see it.
One thing that annoys me, though, is people who start a thread titled "Picture of my new knife" and when you click on it and wait for the thread to download, all there is is a link to the picture which you then have to click on and wait for it download. I know, I sound like George Jetson, "It was an exhausting day at work today... I had to push the button THREE times..."
My other complaint is people posting worthly tiny thumbnails. I can't see anything in a fifty-pixel wide picture. Why even post it? Post a 300-pixel-wide picture and then a link to the big one. At least in 300 pixels I can see enough to know if I want to see the big one or not.
