No problem, happy to help!

I’m not sure how or if Piefed’s UI shows it, but posts are written in Markdown.

When you add an image, text gets added to your post or comment in the following format: ![alt text](image url). So, in your post the “image” is just the string ![bTUDGZRAcKZdXyO.png](https://lemmy.ml/api/v3/image_proxy?url=https%3A%2F%2Fmedia.piefed.zip%2Fposts%2FbT%2FUD%2FbTUDGZRAcKZdXyO.png), which clients (Lemmy’s & Piefed’s web UI and applications) replace with the actual image.

So, if your post/comment editor has an option with something like “source”, “plain text” or “Markdown” in the name, you can enter a description for the image in the brackets right after the exclamation mark.

Fixed image example: ![Unfinished Projects - In solidarity we can build a future that benefits us all.](https://lemmy.ml/api/v3/image_proxy?url=https%3A%2F%2Fmedia.piefed.zip%2Fposts%2FbT%2FUD%2FbTUDGZRAcKZdXyO.png)

The alt text is used by things like screen readers, and even normal browsers, if the image fails to load. So, something like the following might be better:

Logo of Unfinished Projects, with the tagline “In solidarity we can build a future that benefits us all”

If anything is still unclear, I’m happy to answer any questions you may have.

Edit: Lemmy keeps “fixing” “https://media.piefed.zip/posts/bT/UD/bTUDGZRAcKZdXyO.png” to a proxied url for some reason. If you copy the Markdown from this comment, please fix it on your end, as I can’t seem to on mine.

A small nitpick, but could you do something about the image alt text in your post? A filename, especially a non descriptive one, is not exactly great for accessibility.
