to resize an image, theres a couple ways to do it.
google free online image editor, its a pretty standard feature
some upload sites allow you to set a resolution before uploading them
this (
http://www.irfanview.com/) site lets you download an extremely powerful image resizer for free. i havent used it in years though, so it might've changed since then. read the installation fine print and the website and all that.
photoshop.
paint can function in a pinch
edit: nice job with the pictures, they look like you put thought into them. like the ryan cambell looks good
