&lt;p&gt;You can't have a transparent profile avatar image in Slack in 2022-11-29 :(&lt;/p&gt;
&lt;p&gt;This was requested in 2014, but did not change in 2017 and 2022: &lt;a class="reference external" href="https://twitter.com/slackhq/status/533006882588622848"&gt;https://twitter.com/slackhq/status/533006882588622848&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;Manually set an image via &lt;tt class="docutils literal"&gt;curl&lt;/tt&gt; (if you have a token with scope &lt;cite&gt;users.profile:write&lt;/cite&gt;):&lt;/p&gt;
&lt;pre class="literal-block"&gt;
curl -s -XPOST https://slack.com/api/users.setPhoto --form token=xoxp-secret --form image=&amp;#64;myimage.png
&lt;/pre&gt;
&lt;div class="section" id="profile-image-with-the-current-time"&gt;
&lt;h1&gt;Profile image with the current time&lt;/h1&gt;
&lt;pre class="literal-block"&gt;
while true; do echo -n .; convert cweiske-orange.png -fill blue -gravity Center -pointsize 130 -annotate +0+0 $(date +%H:%M:%S) -resize 128x128 temp1.png; curl -s -XPOST https://slack.com/api/users.setPhoto --form token=xoxp-secret --form image=&amp;#64;temp1.png &amp;gt; /dev/null; sleep 3; done
&lt;/pre&gt;
&lt;/div&gt;
&lt;/div&gt;
