I want to suggest that someone who knows could pin an announcement about posting photos to Interchange as to proper sizing, so they don't get posted way oversize, which frequently happens. I went looking for guidance this morning and could not find any here. Also, when I tried to upload a photo, the progress bar just kept running and never completing. Thanks.

I would add to the instructions in my reply that the maximum dimension is 1024 on RyPN, so I usually set my largest dimension as 1023 when resizing.

Thank you.

If it helps, I post images at 800x600 pixels or thereabout at 72dpi. I think you can go as high as 1024x768 at 72dpi. They'll post at a smaller size and will be displayed a bit larger when you click/tap on it. IIRC, the max file size limit is 350K.
