If you have a photo that is over 300K in file size, the maximum for this website, you can resize it with a great, free tool from Microsoft.
It's easy to just click to resize your photo before attaching to posts.http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
Once downloaded, you will have a resizing option in your right click menu. Just select the photo or group of photos, and resize to "small", which is the internet default. You can contact me if you have questions by using the feedback link on the bottom of the page.
Enjoy!!
