Assuming the image uploaded correctly to your Phototbucket account it is very easy to place them on here. You should have 4 file names underneath each small picture in Photobucket. Click on the one at the bottom. It is an image file, .
My photobucket account automatically copies the file when you click on the last file. You see a small yellow box pop up when you do it that says copied.
If you did not see the box pop up then highlight the file and right click on it and select copy.
Then all you do is go to your post and right click and select paste. If copying more then on file then make sure you hit enter after you paste. The paste the next picture on a new line below the one you just pasted. Kinda like starting a new paragraph.
Hope this helps but the biggest thing is selecting the [IMG] File to paste in the SVTP Post.
EDIT: Mixed up my left and right LOL. Post now fixed
