Trying PNG

Now I am trying a PNG file... I am uploading a file that was a JPEG (~100 kB) and converting to PNG at best quality (190 kB). Does it work??

update: working from the original file, resizing and converting directly to PNG, the file size is ~215 kB, but the quality is better. This is an unfortunate but helpful work-around (suggested at the blogger helpdesk by "DarkUFO") because the file size is so large, but at least the building borders don't look horrible and skies don't look patchy
