One of the steps on Stack Exchange's road to HTTPS is the replacing of embedded
http:// images with secure ones. This has been done automatically for a lot of images, but there are some that can't be automatically fixed. These were rewritten in the HTML (but not the Markdown source) to be text links instead of image embeds. It would be good to go through the affected posts and make images display correctly, or remove the link debris if they can't be restored.
Since there seems to be a problem with the CrowdCrafting task's data, I used this SEDE query (slightly adjusted from this version by Jefromi) to find a few hundred posts that may require our attention.
To continually track our progress, we have a Google spreadsheet. (Even though all the links have
/q/, answers are included too.) The Status column is editable by anyone, so please note your work there as you go along.
As usual when doing big batches of edits, try to avoid flooding the front page, and please try to fix all obvious problems before submitting an edit.
