I host my images for mountain trips here
Here is the kind of script I use to transfer:
!/bin/sh
rsync --exclude '.git' -arvz cmaimages/ \
[email protected]:~/public_html/cmaimages
Thumbnails were created with ImageMagick, like so:
magick mogrify -resize 800x600 -path thumbs/2009 2009/*.jpg
Files from 2005 and before simply have copies of the original file in the thumbs directories, because in all cases, the thumbs/ directory was larger than the original year directory!
