Embbed images in [img] bbcode tag will now show up randomly in the Featuring Member's images as well.
Note: I highly recommend using imgur.com to upload your image (If you're not attaching your image as a GL upload attachment).
Other sites seem to come in and out of existence over time.
images on gimpchat are sometimes not shown because gimpchat.com tries to prevent people from hot linking.
Other than that if you notice any images not showing on the Featuring Member's image, click on it it'll take you to that post and if that post is yours, you can edit it by using 1) an attachment or 2) upload to imgur.com (then right click and Copy Image location) and use that in your [img] bbcode tag.
I am not sure what you mean. I don't plan on upgrading anything.
If you're wondering about the security thing on the lock before site name....https means site is secured but some images aren't secured...that's just the nature of including images that aren't all from https if one of them is http instead of https then the whole page gets the exclamation mark lock icon.
