I dont use that way anymore, its okay to use for the first round if you cant get pics loaded, but if you want to add other pics you have to delete, and it deletes in your thread.
You can use Photobucket, upload from you file, dont have to resize to upload. Then if its uploaded, you can go and click on the pic, and there will be a resize button just under the 'click to add title', and resize to 'message board- 640 x 480 and just click on that, it will rezise itself. Then you go back to your album and click on the third one- once the 'IMG Code' it will say copied and you just go back to PF and right click to paste. Its real quick and easy, you may just have to get someone to check for some functions to change to get it working, my brother did mine, i know nothing of puters

.
But its really the easiest, no uploading from the url thing or a attachment, its just copy and paste!

Hope this helps, its really very easy, just get someone to fix the function thing, cant remember what it says, but it pops out in a yellow line above PF and says something, you just need to get that gone.
