You almost got it, could be the error when you try to post here.
Try this one:
After you got photo upload, next is to select the 4th line with FORUM CODE and you see the URL address in the box, highlight it (put mouse on and click it, it'll be blue color), then you can COPY and PASTE it here.
You can click SHOW PREVIEW, if you got it right, the photo will show up on PREVIEM page then you post it here.
I am waiting for your posting the photo here. Some more questions? Don't hesitate to ask. (Remember,there is NO stupid questions,all questions are smart one). Some other reader might know and give you better answer and might be easier to follow.. You never know.
Ok, after you paste it here, it'll show additional line at the bottom (almost like another URL address)The line starts with: Uploaded with; You can delete this line (this bottom line ONLY) and then click on Preview again . If it does not show up on preview page, that means you got it.
