create alt text for all amheida images

[paregorios]

governing epic: #408 migrate amheida content from standalone website to the research section of isaw web

Arbitrary manual checking reveals that some images in the Amheida section have good alt text, but others just have the names of the image files. The latter condition is a WCAG violation and must be corrected before the Amheida materials can be published.

Steps:

• determine which images need alt text captioning (make a list)
• get alt text from the amheida team
• insert alt text through the plone (ideally the amheida team will do this themselves)

Assigned this to myself to do the first step: make a list of all amheida-related images and whether they need alt text or not. Once this is done, we can publish all portions that don't include PDFs or videos.

It looks like there are about 70 images in the amheida portion of the site: https://isaw.nyu.edu/members/te20-40nyu.edu/amheida-images/. What the collection here doesn't do is tell me where these are surfaced and whether alt text has been applied in those locations.

Page-by-page inventory of embedded images

A checked box before a page title means that page has been inspected for the presence of images. A checked box before an image means that image has been checked for compliant alt text.

It looks like there are about 70 images in the amheida portion of the site: https://isaw.nyu.edu/members/te20-40nyu.edu/amheida-images/. What the collection here doesn't do is tell me where these are surfaced and whether alt text has been applied in those locations.

FYI @paregorios - there were many unused images on the site but I don't think I uploaded any of them. Aside from the plans, maps, and satellite areas I cherry picked the images that were actually used on the homepage, CUNY Excavations, El-Deir Partnership, and Local Community pages and uploaded them manually. IIRC there is a file in the on the original site in the inc/img/sat area that contains descriptions of the satellite images (or maybe I am thinking of the maps and plans) but I think those descriptions were also present as text on the page.

Bummer about all the alt text work...

[skleinfeldt]

And I meant to say - I did not do anything about alt text when moving stuff as I had no information on the images (aside from that text file info and the captions which were already on the relevant pages.)
