As a keen photographer, I've used most of the photo hosting services over the years, flickr, smugmug, google photos, etc,
and the ones I've found the most useful are Zonerama , closely followed by yogile
https://www.yogile.com/.
I upload my Z3 photos here:
https://eu.zonerama.com/kudos/Album/10266483
And more general car pics here:

Zonerama is completely free to use, and you can view the GPS location of the photo on a map, along with all of the camera settings used.
Yogile is only US$45 per year and is ideal for posting pics of family or club events, like weddings, parties, car meets, etc, where there are lots people who you want to share the photos with.
And these two links are pretty much direct replacements for imgur.
