Sorry about your challenges Steve. Please email your photos to me or Carl and we will get them sized and posted asap.
We could certainly accept larger photographs on this website, but the issue is twofold. First, the current size limit of 256kilobytes basically is what fits on a webpage and anything bigger requires scrolling to view the photo in its entirety. That is somewhat inefficient particularly in light of issue #2, the more important one, which is money. This is a free website for the users, but not free to Carl who pays the monthly hosting fees. Those fees are a function of the amount of data stored on the website and pictures hog lots of memory exponentially with increases in their size. Carl has never complained of his hosting responsibilities and I do not want folks to think he is a sore sport, but if we put several multi megabyte pictures up on this forum, he is going to have a higher monthly fee to pay which could very, very quickly translate to hundreds of dollars more per year.
As for auto-sizing, that is not an option in this software package we are using. It runs many, many other forums and is also free to us, but it doesn't have unlimited flexibility in its settings. Basically it allows us to restrict the attachment size to whatever limit we want, and doesn't do anything else to help us manage file size.
Facebook and other sites get plenty of $ from advertisers and others who mine your data and doesn't pay a third party for storage. What they can do is a world of difference from what we can do here. I wish we could do more and we will when those options become affordably available through this package or another one.
