Photobucket, Imageshack. Find a picture you like. Right click> Copy link adress> come to the TGT post box and click the picture frame icon, then click "From URL", then paste the link adress, and then click OK.
Do that for every picture, or just copy the link adress and past it in between the middle two brackets of the text below.
When you clock on the 'Inset Image' icon above the reply block, it will ask you if you want to load pictures 'From Computer' or 'From URL'
Select 'From Computer' and when you hit 'Select Files,' hold down the <Shift> key and highlight all the photos you want to add. It'll look like this...
All the files should be listed, then click 'Upload File(s)' and they'll be attached to the bottom of your post!
I still prefer PhotoBucket, just create an account on that site and load 'em up!
