ITS A LOT EASIER IF YOU PRINT THIS OFF FIRST AND THEN FOLLOW THE INSTRUCTIONS
There are lots of places on the net you can store your pictures on to be used as URL links, and this is one of them. This site is FREE.
You will have to register with them. Answer all the questions, and give yourself a user name and password. Click on the following site:
http://www.photobucket.com/
Do the registration thing, and then upload your resized photos to their site. Once you have uploaded them, you will see a list of all the photos that you have there.
To load them, Browse your files, click on the picture, then press the 'submit' button ....Under your picture are three tags. The one marked URL is the one you want. Just click over it to highlight it, copy the location...MAKE SURE YOU GET THE WHOLE ADDRESS,,IT IS REALLY LONG and then click on that little kinda yellow tag at the top (looks like it has a mountain or something on the bottom of it (it will popup a 'insert image' tag, delete the http and then click paste so that the whole site is there. click 'OK'. That should be it.
If the resizer worked properly, you should see a picture. You can even put more than one downsized pictures on the same post. There is a maximum that you are allowed, it is based on picture size in space used.
