Gavroche, if you are using photobucket it is simple.
Open the photo you want to share in Photobucket.
On the right is a box which says
Links to share this photo.
Select IMG....it is at the bottom of the box
SELECT ALL
COPY
Then open the text box in Cycle chat and press the text box and select PASTE.
Your photo will appear as a link. When you post it the photo will come up on the site. I hope this helps.
