I posted a large image in the funny stuff thread earlier and it didn't get scaled down for the post. It also seemed to ignore me specifying a width in the img tag.
Let me see if I can repro here...
OK, I've figured it out. If you wrap a large image in a spoiler tag it breaks preview, and then when you save it there is a delay of a few seconds before it gets resized to a reasonable size.
It's not a huge bug, but it'd be useful if the preview window gave accurate results.
Could one of the mods please delete/close this thread? (Paging @boomzilla.)
This post is deleted!
That's a coincidence - that's the exact same image I used...
