The attachment method is a PITA IMO anyway. It's a lot nicer to upload the pictures and then link the IMG tags here.
And sometimes some of the sites like image shack seem to be causing pop ups when linked away to them, YUKK!!
Photobucket.com seems to be the best still.
You can upload ANY size picture you want. just set your preferences on photobucket to (forum) 640 x 480 and it will resize them on the fly as they upload! That's right. You NEVER need to resize them first before uploading.
Then one click under each picture you uploaded will copy the [ img ] tags to your clip board and then you can paste them directly in here.
Then when we view your post the pictures display like this...
Nice and neet. And the viewers don't have to click on attachments or be redirected to another site with pop ups.
