Download Slack Profile Pictures / Images

Download-Slack-Profile-Pictures.js

// Enter slack in the browser. https://{insert your team name here}.slack.com/messages/
// Click on the channel you want.
// Click the information icon.
// Expand the members dropdown.
// Click "See All Members"

// Paste the next line into the console, hit enter.
var imageList = new Array()

// If your channel has more than 19 members, the list won't display past that. It also unloads them from the state as you scroll.
// Paste the following section into the console, hit enter.

var $slackUser = $('#channel_membership_dialog_scroller').find('.member_item')
$slackUser.each(function(i, e) {
	var $this = $(this)
	var $memberImageElem = $this.find('.member_image')
	var $memberThumbnail = $memberImageElem.css('background-image')
	var $memberThumbnailUrl = $memberThumbnail
		.replace('url("', '')
		.replace('-24")', '-500')
	imageList.push($memberThumbnailUrl)
})

// If your list is over 19 members, you'll have to drag the list scrollbar down to force a state update of member. Run the above script again (lines 13-22).
// Repeat this until you've gone through the whole list. It's okay if you get duplicates.

// After your list is done, paste into terminal, hit enter.

copy(imageList)

// Open editor, paste newly copied imageList from console into a new file, save as imagelist.txt
// Remove all quotes, commas, and brackets so urls are on one line a piece (a quick find/replace works)
// In terminal run the following:

xargs -n 1 curl -O < imagelist.txt

// The images should start to download. It will merge duplicates.
// You'll need to mass file rename this to add `.jpg` as an extension.

For the 2023 members list dialog I adapted this to the following:

var $slackUsersImages = document.querySelectorAll('[aria-label="Members in channel"] [data-qa="member-entity__avatar"] img')
$slackUsersImages.forEach(function(el,i) {
	var $memberThumbnail = el.src
	var $memberThumbnailUrl = $memberThumbnail
		.replace('url("', '')
		.replace('-48', '-500')
	imageList.push($memberThumbnailUrl)
})

To download I then used copy([...new Set(imageList)] to get uniq items only and wl-paste | jq -c '.[]' | xargs -n 1 wget to download

Thank you for this!!

After wrestling with the Slack API and trying to make a Slack App just so I could run a script...
...this web scraping approach is a breath of fresh air! 👏

I updated this script in a few ways:

• duplicate entries are automatically removed (thanks to "Map"!)
• scrolling auto-adds entries to the list
• name files after each person's name
• copy-paste a list of curl commands directly; no file needed

My updated version:

I'm surprised it even still works. A 5.5 year old script. :-)
