<h3 id="downloading">Does this site prevent people from downloading my pictures?</h3>
<p>
This website does not go out of its way to prevent people from downloading pictures, and
nor will it pretend to. This is actually a very difficult problem to solve in the year {{.YYYY}}.
<span class="tag is-success">Updated Jan 10 2024</span>

I <em>could</em> add some JavaScripts that prevent right-clicking on my pages so you can't
just "Save image as," but this would only deter desktop (mouse &amp; keyboard) users and is easy
to work around. I <em>could</em> place a transparent image over top of all your pictures like
Instagram does and if you try and save it, you just get a one-pixel transparent GIF; but this
is trivially defeated by any novice web designer by just right-clicking, "Inspect element" and
deleting it from the web page to get at the photo it was protecting.
As of November 2023, the {{PrettyTitle}} website does discourage the downloading of pictures
to the limited extent that a web page is able to. We have a right-click handler (long press
on mobile) where if you right-click on a photo anywhere on the site, you are shown a pop-up
message to "please respect our members' privacy" and a reminder that it is against the rules
to download and share images from this site elsewhere. We also have a script that inteferes with
dragging an image off of the page and into your URL bar or another application which helps to
protect pictures from being easily saved.

<p>
And people can always just screenshot the whole web page - and a web page can't do anything
at all to prevent that. With mobile phones this is an especially easy and common thing to
do. Any mild measures this site could take to deter downloading would only provide a false
sense of security, which is worse than having no security.
You can see this in action by attempting to right-click, long press, or drag the image below:

There are risks inherent with putting a picture on the Internet. This website does provide
some controls you can utilize as to <em>who</em> will see the pictures you upload:
<img src="/static/img/shy.png" width="48" height="48">
</p>
<p>
However, a motivated individual can <strong>always</strong> circumvent these kind of restrictions
and download a picture if they really want to. There is no technical measure that a website can
take to prevent this entirely: because at the end of the day, they can always just screenshot the whole
entire web page which is especially trivial and common to do from mobile devices.

There are risks inherent with putting a picture on the Internet. This website <em>does</em> provide
some controls you can utilize to limit who is allowed to see your picture in the first place, to
those who you think you can trust not to download your picture:
