This is the original Lightbox script that introduced the concept of overlaying content on top of an existing page. The code is over 10 years old and I wouldn't recommend anyone use it, but I've kept it here for posterity.
The script narrowly focused on displaying images and nailed a couple of things out of the gate that helped it gain traction:
- 🛠 It was super simple to implement. The focus on developer ergonomics was less common at the time.
- 💪 It degraded gracefully if Javascript was disabled or unavailable, a real possibility at the time
Over time, it went on to spawn 100s of imitators and become a standard pattern on the web, with the term lightbox added to the lexicon. Wikipedia/Lightbox_(Javascript)
In December 2005, I began tinkering around with the idea. I was redesigning my blog and my new design introduced a different column width for the content. This caused the images in the posts to overflow, unless I resized each one of them to fit the new width. I did not want to have to do this every time I tweaked my blog design, so I began to explore alternatives to displaying images.
And quickly during this ideation phase, Lightbox was born. I replaced the full-size images in the post with thumbnails and had a click reveal the full-size images. But this time, the images would display above, being overlayed on the page, and not have to worry about the content's column width.
I shared the script running on my blog to a couple of coworkers and they were mildly impressed. I thought I was on to something so I kept going.
Right before the new year, I emailed a few of my favorite design bloggers and shared my script with them:

Hello,
I've written a little script to help people, mainly bloggers, handle large images. Its a little faux-popup effect with Javascript.
It might be useful for you, or not, either way take a look: http://www.huddletogether.com/projects/lightbox/

Hey - looks cool! I think I noticed a bug though in Safari / OS X. The image loads great the first time, but after closing it and clicking the same thumbnail again, I get an endless progress bar.

More positive feedback, and the first feature request:

The script looks nice! I like that the popup image fits into the window size. The only thing I would add is a way to close the overlay before the image has loaded just in case a user doesn't want to wait or if the image doesn't load at all.

One of the biggest challenges with the new pattern was noted here in the first week:
On Dec 30, 2005:
I wonder how many folks visiting a page running your image script will do what I did after clicking and getting this big picture that obscures everything else...click the back button and completely leave your site?
Perhaps there is a way to cue them that they need to click on the image a second time to return to the original page.
Good luck!
The script was shared out by a few of the people I emailed directly and started picking up traction incredibly fast thanks to del.icio.us, a social bookmarking site which was popular for discovery at the time.

I found the Lightbox JS demo today from del.icio.us, and I just wanted to say how impressed I am with it. It looks good, it's easy to use, and it's very unobtrusive. I would like to use it in a site I am developing for my university's student newspaper (Case Western Reserve University). Is it this okay with you?

I just learned of your very interesting lightbox script. I really like the way you are stretching the dimensionality of the web page.
People were already beginning to imagine how this pattern could be extended:

Great script!!!
It’s way much safer than a pop up and it looks pretty neat…
I was wondering if theres a posiblity that I could load another html instead of an image???
For quite some time, I attempted to help everyone who emailed my with their support issues:
On Jan 3, 2006:
I need some help if you have a moment. I have implemented lightbox on my blog and it is not working just right. I click on the image and the loading graphic comes up but the larger image never appears.
Any ideas? I am on Wordpress v2
There were lots of support issues, but people were generally nice and I was happy to help.

Many thanks for this nice scipt, it's fantastic! A nice replacement for all annoying pop-ups. I was confronted with a strange bug in Firefox 1.5. But it's not your script, it is some incompatibility with a css syntax in my script.
I also received a ton of thank you emails, each one of them was a treat!
On Jan 7, 2006:
this is just a cliché thank you email! loved the "lightbox", really clean and classy. used it on a website of mine (small icon on the side of each photo for floating over the page, to allow for both traditional and floating over the page viewing):
I have about 10,000 emails related to Lightbox in Gmail and the history so far captures the events of the oldest 500. I hope to dig into more over time as it is a fun walk down memory lane for me.
