With regards to resizing pics --
if you are using a PC (not a mac) and it has MS Office loaded usually it comes with an app called Microsoft Office Picture Maker... if you open your photo with this and click on edit pictures, then click on compress pictures, then you can chose what size you want to edit it to...if I select documents I can edit a 3.4 mb pic to 481 kb -- takes milliseconds to upload then!
Maybe this will help!!!
