To remove links from pictures....
First of all, when you copy and paste a picture from another site that is bandwidth theft, you should always save the picture to your own computer first, upload them to your group album if you have one or your photobucket or foki site before adding them to your post. Once you have added them you can remove the link so they don't go back to your photobucket account or whatever site you use. My tag below is still linked to photobucket, but I can remove that easily.
1. Click on the picture so you get the little nodes on the corners or you can highlight it if you wish. Either works.
2. Again click on the link icon above, repeat the same steps for this as you would for removing a link from text. I don't think just clicking on the end of it and hitting backspace is going to work for this one. You will need to be in the link's window in order for it be removed.
Once I post this you will see that it is no longer linked to my photobucket account.
I hope these handy lil tips have helped you and if you have any further questions please don't hesitate to ask.
