Then perhaps the forum software doesn’t like me
Thinking about that a little further, I wonder if my png images are ‘backed-up in a queue’ somewhere in the system … so the jpeg is sitting behind them, awaiting its turn to get posted ??Bill’s patient analysis of what’s occurring might be interesting …

Thinking back, some of my first lost images were .png as my screen snipper had changed its default from .jpg for some reason and I hadn’t realised; I wrongly surmised that it was the image format that was the problem and reverted to .jpg.
It’s not been the case for all my missing images though; some .jpg ones have gone walkabout too, sometimes reappearing later, sometimes not.
On one reply my .jpg image did come up just as a place-marker, but by the time I realised, I was outside the edit time window.
I followed it straight on with a new post using exactly the same image, which was still stored on my clipboard; it displayed correctly and immediately.
Some time later the original image appeared in the initial post where the place-marker had been.
From that I don’t think it’s the image, or its format, which is the issue, as it would show each time.
Rather it’s a glitch sometimes/somewhere whilst it’s being submitted, or maybe when converted from png to jpg, or the .jpg re-sampled.
I believe png isn’t a lossy format, jpgs are, but both will still need re-sampling for forum storage/display down to 96dpi. This is separate to the maximum pixel width, so a 200 pixel wide image won’t need changing width wise, but will still need reducing to 96dpi.
What I haven’t yet tried is uploading a 72dpi image to see if it’s raised/re-sampled to 96 when stored/displayed.
For those unsure about the differences, and I’m certainly no expert, there’s plenty of info on the web; this article compares png, jpg, & jpeg
Edit, obviously the above text doesn’t contain any images to process, but still takes quite some time to submit after the button is pressed.
I still wonder if that delay isn’t due to posting time, but is caused by re-compiling the “Latest Replies” list, which recompiles with every screen refresh.
