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.
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
?__a=1 and it will ‘dump’ a `xml’ of the picture or gallery,
like the following one for this
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).
Using it, I was able to then consider using some Gallery Software to get them rendereded.
https://galleria.io offers a nice gallery, which uses jQuery and also
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.
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
