Is there a way I can put screenshots up from my computer into the forum?

Also, the forum keeps asking me to log in every now and hen when I switch to a different page (such as if I'm editing a post etc), is that intentional or is there something wrong there? (I sometimes end up having to log in each time I visit a different page.)

1. To post images, they need to be hosted somewhere on the internet. Most ISPs have webspace which you can use.

2. This is because of your security settings. With IE, you need to allow "invisionfree.com" under "Privacy" in your settings.
