if you sign up to http://www.imageshack.us/ (its free) then go to my photos, on the left hand side it will say upload multiple images click that it will bring up an other menu on it it will say browse click this and select your images. under the browse it will say resize images select what size you wont then i would suggest 640x480. when they have been uploaded right click on the image and veiw it when your image comes up right click on it and copy image location. then on thl just paste it into the insert image icon.
hope this helps
