Thank you for the feedback, Geraint.
Just to note. I have Firefox and have never had an issue like this occur.
I use firefox and it occurs once or twice a week?
Edited to add: my images are usually in either my ideas thread (one on one wanteds) or in the roleplay forums. And it has happened in both places.
Without more specific information about a specific incident, I couldn't say why it happens for you. I've never run into this problem.
The last time I had it happen was actually, yesterday, with this post
and with that particular image have not had it happen the entire time I've used it (since April).
I formatted it like this and checked it before clicking preview (and it was just a copy pasta from an earlier post, that I have never before had an issue with).
I just now previewed a post with it in and had no problems. Though yesterday my preview was this (somewhat different from najlah's issue) and it is this that happens every so often:
Now that was with directly copying this from a previous post that I had opened.
Does that help at all? lol Its not really that big of a deal, I generally just wipe it clean and paste again without an issue. But, it leaves me curious as to why it happens. ~shrugs~
