Whenever I try to view a post where a user has attached a picture in the post it comes up with this msg: "btcointalk.org image proxy Invalid Image" At first I thought this was something wrong with the image posted, but it has happened too many times and I think its something wrong at my end. Anyone know what is wrong and how i can fix it?
Did you see what image host they used? If those users used the imgur for image host then that is the cause you are seeing thus error.
You can also see this topic here already discussed about it.
