welcome to YT! you could always upload your pictures to an online photoalbum like
Fotki: Share and Print Your Photos | Fotki.com DropShots - Free Video Hosting & Online Photo Sharing. Upload Video Now! Image hosting, free photo sharing & video sharing at Photobucket
and it will automatically resize for you...then using the image url you can then upload to YorkieTalk.com
also read through this thread, there is a freeware program called photoscape that i think will allow you to do this also.
