Introduction

I was looking for an alternative for my (this) blog and hold pictures. I’m a lego fan so I wanted to get some pictures uploaded but without bloating the site.

In the article Lego Mini Cooper MOC I did add lot of pictures, same for Lego Chinese dinner and Lego Dragon Dance.

I was checking and how telegram does handle some links and found that Instragram ‘links’ get expanded to list the images inside directly to see if that could help in a task I was helping at Pelican-Elegant theme used at this site for creating a gallery.

Instagram and multiple pictures

While doing some research, I found that apparently, to an instagram url you can append ?__a=1 and it will ‘dump’ a `xml’ of the picture or gallery, like the following one for this picture:

In this case, the generated JSON, available at https://www.instagram.com/p/B7yh4IdItNd/?__a=1 contains the information we required for getting image size, thumbnail, etc

The important there is that from a gallery ID, we can get a JSON without requiring any API key (which is required for Flickr for example).

I’m not an expert in JavaScript, but I did something which was useful enough to get the json, then process the internal code and separate in two cases, ‘gallery ID’ with one or multiple pictures.

Using it, I was able to then consider using some Gallery Software to get them rendereded.

Galleria.io

https://galleria.io offers a nice gallery, which uses jQuery and also accepts a json as input, so it was more or less straighforward to convert from the json from Instagram to what Galleria.io required.

I used that to get an intial draft to be added to Pelican-Elegant, but as the goal in the project is to remove dependency on jQuery it was discarded.

However my personal research came part of another website that even not directly from instagram, takes a good advantage of defining a json of images for showcasing pictures.

PhotoSwipe

While discussing about Galleria, Talha from Pelican-Elegant found two other projects and it was decided that PhotoSwipe provided nice features, mobile usage like pinch-in and pinch-out.

Photoswipe required extra steps like creating a div and using html tags for putting pics (check the official documentation for Pelican-Elegant Galleries)

One of the main problems was getting image size required (Galleria.io didn’t required it), but when using Instagram pictures we can grab the information from the JSON.

Finally with the help from Talha, we got it also working with Instagram Gallery Embed Instagram Post

Enjoy!
