Cannot post images inside a spoiler

OrangeYambles​  The post you linked is from the previous site, which was somewhat more cooperative on the subject.  But I did get an image in a spoiler to work last fall:

⚙️[PC] Crashing Guide - Start Here | EA Forums - 12636804

I believe I edited the HTML directly.  Do you have that option?  It wouldn't show up in replies, just the original post, but I'm not sure whether it's available for everyone.

That would be great. I'm trying to organise my post better so I only need it to work on the main thread itself, and not replies. 

There's a "source code" option if I try to edit my thread. Are you able to share how yours is structured? Maybe I just need to mimic the same layout.

OrangeYambles​  Source Code is what I use too, but I don't know HTML well enough to remember how to do everything off the top of my head.  So what I often do is click the button for a given formatting tool in rich text mode, then switch to source code to see what it looks like, and add more there if necessary.

In your situation, I would add the image first, plus any additional text you're including, then switch to source code and add the spoiler tags around it.

This is the HTML version of that part of my guide:

<li-spoiler label="[open the spoiler with the arrow to the right]">

<p class="lia-linked-item">This is likely due to OneDrive syncing your files, although other cloud-syncing apps can be at fault.&nbsp; For OneDrive, try pausing syncing, which you can do by right-clicking the cloud icon in the lower-right corner of the screen, or sometimes the icon is hidden in the Tray (^ icon).</p>

[the other text I included]

</li-spoiler>

Sadly it didn't work. I copied the whole block and pasted it directly into the main post here too, without changes.

OrangeYambles​  I copied the same block into source code and posted it, but I edited a bit first.  Namely, I put one line above the spoiler and one just before the end (both looking like this: <p>stuff</p> ), and I deleted the extra line breaks.  Otherwise, the source code might not be read properly.  The post showed up fine in this forum, although I removed it later.

Anyway, I've asked someone else if they know what's going on, whether it's a permissions/rank issue or something else about the site.  I don't have an alternate account to test with myself.
