I will dude, can't wait to see your bike!
You need to open an online pic hosting account. Easiest in my opinion is photobucket.com
Once you have an account with them (it's free) you upload photos by opening up the "upload " window and dragging and dropping photos to the account. They take a while to upload, so only do a few at a time.
Make sure the album you want to share is marked as public then display the photo you want to share. A box opens up on the right hand side of your screen with a series of link codes. Click on teh bottom code entitled "IMG" and the code will automatically copy to your clipboard.
Open up a reply dialogue box on Cyclechat and right click paste or ctrl V to paste the IMG Url into the box. When you send the post the photo will display.
