I know this is kinda old now, but fyi recently Ive had one quote that skipped reposting the picture I wanted to refer to, and another couple of posts where I couldn't remove a picture from a quote nor any text.
Actually, not being able to remove the photos in a quote has been common a long while. I'm guessing that is the root cause of people falling out of the "short quote" mindframe. They just couldn't make it go away.
I edited out all the uneeded space eaters in quotes until I lost the ability to edit them out.
I normally edit out a quoted photo/text with the backspace key.(droid)
Sometimes the backspace key won't change anything but what I type.
If I backspace in quotes photo or text, it just reloads whatever I erase and moves the cursor to the end of the quote.
FF, Kiwi, Brave, Duck Duck Go and other browsers. (these work best for me here... FF only so/so. Google spellwreck is better behaved on the other browsers that use Google base code, than Googles own browser.)
