Dgirl, I don't know if this works for Flickr, but you could click
this image, then a small menu appears, you can paste your image URL inside.
The image URL should be apearing between "[IMG]" and "[/IMG]" in your message.
When you post your message, the image will appear, you can go to "go advanced"
and see a preview.
You can copy the image url by rightclicking the image you'ld like to post.
Hope this helps,
And keep up the good work, looking forward to see your finished model!
Jerry
