Can't upload an image through define pages editor

Please help! I am trying to upload an image using the DEFINE PAGES EDITOR.

The path to my image is: http://www.mydomain.com/public_html/includes/templates/myown/images/beanbag in dollhouse setting.jpg

I enter the address into the little pop up window where it asks for the url.

This is what I get:

404 Not Found
The requested URL /editors/htmlarea/popups/www.heavensentminiatures.com/public_html/includes/templates/myown/images/beanbag%20in%20dollhouse%20setting.jpg does not exist.

PLEASE ADVISE!:yuck:

First rename image with out spaces then try

http://www.heavensentminiatures.com/includes/templates/myown/images/beanbag%20in%20dollhouse%20setting.jpg

Adjust the above after removing spaces to what you end up as the image name

Once again Kobra YOU SAVED THE DAY! You are so helpful! Thank you! Do you think the name was too long with the spaces or what? Because after I took out the spaces, BINGO! :) You rock!

Do you think the name was too long with the spaces or what?
LINUX doesn't like spaces but will usually resolve - not in this case

Hey Kobra...thank you so much for your help! Can I ask another?
When I type information on one of my category pages, the "add to cart" option moves all the way to the bottom of the page. Is there a way I can make the "add to cart" option stay up near the top of the page so people can see it?

Nevermind, I fixed it!
