I just click the "Quote" button, erase the previous post and the quote commands and enter my post.
If it's a post I need to add more graphics to, I open a new tab (with IE7) and get the image info from that tab then add it to my post where I need it to go. If it's an image on BB, I right click on the Gallery link then click "Open in New Tab" that way I can toggle back and frorth between the two windows and get what I need.
And don't forget, if you use a text editor or Word, you can copy the link for the image and place it in the post before you post it in the thread thus eliminating the need for multiple edits.
