It can be confusing posting pictures here, there are some good directions in the help section:

For my computer/browser/camera combination, I find it easiest to use the defaults given at this size to reduce the file size of my pictures.
https://www.reduceimages.com/
Download there and upload here.
I reduce my internet window to half size and my file manager window opens above it, then I simply drag it from my file/camera to the correct spot on the linked page. Make sure to download it, not just reduce it!
It took me much longer to figure out than it should have that there is an "Upload" button to the far right of the attach screen -- you have to widen the window to see it, it is still set in the vertical default of the old boards instead of the horizontal setting currently used.
edit: A couple of weeks ago at the thrift store there was a lovely black with good decals Free Westinghouse in a stand for under $2.00 (yes, $1.79 no missing decimals) broke my heart to leave it but I just have no room.
