How to increase image description space

Have you tried using Captions? IIRC you can make them longer…

I assume Captions is a plugin. Correct? But what does IIRC mean? Thanks in advance!

No, captions are built in, but I had ’em backwards. Descriptions are longer than captions. How long are these poems?

This is one of the longer poems:

Your sinews are locked in contorted embrace, spellbound reminder, perhaps, of some decades-old transgression. Were you unwilling witness or wilful perpetrator? What forbidden sight did your eyes behold? What sacred law was shattered in the wake of your careless momentum? No matter which, you seem bound by the chains of some unhappy past. The gods are cruel and unforgiving.

Yes, I’m using the Description box as opposed to the Captions box because it gives me more space. (Also, had problems with Captions code, not sure why.)

You may need to just put the text of the poem in the post, rather than in the image, at that point.

Or a plugin like this: https://www.ads-software.com/extend/plugins/long-description-for-image-attachments/

Would you happen to know how this plugin works? I’ve gone ahead and installed it, but am not clear on what I do next. Documentation is very poor.

Nevermind, I’ve figured it out. Not my ideal solution, but good enough. Thanks!
