Glad you are enjoying zoom capable pictures! I have been posting high resolution going back to MLS days. The old software allowed a link to be embedded in a photo, and I used that to link to a high-res version. It was a lot of work creating two sizes of every picture and uploading them all to my web space. I asked if folks ever looked at the high res versions and got an overwhelming No response. So I stopped.
More recently, even in the old version of LSC, most posts had pics at 2048x1536, or at minimum 1024x768. They would display at 800x but could be opened in a new tab at full resolution. I doubt many did that either.
Now that the actual resolution is displayed and a simple click gets you a larger image, I think the larger images will be viewed more often.
