Babyonboardnov and becklyn.........
I believe this is what you are looking for. :d
take your pic that you want to show and upload it to your picture hosting website that you chose. I have chose imagestation. It's free and you have unlimited storage space. If you don't know which folder your pick is in on your computer, there is a browse button. Hit that and it will allow you to go through the folders on your computer.
Open two browser windows, one being open to e-health forum (logged in) and the other one imagestation. Go to the forum you would like to post your pic. Then, when you click either "post reply" or "new topic", it'll take you to the reply window.
To post your pic, go to the imagestation screen. Right click on your uploaded pic. Click properties. Where it says "url", highlight and copy everything you see there.
Go back to the e-health forum reply screen. There will be a few boxes with things in them.......Go to the one that says "img", it should be second from the right, near the top. Click that once.
Making sure there are no spaces, right click and press paste. This is your address of your picture you want to show. Hit the "img" button again.
If you notice there is a jpg.Orig.Jpg at the end of your pic, take off the .Orig.Jpg only. Make sure there is a .Jpg at the end. For some reason, some people have problems with the .Orig.Jpg being on the end of their pics. It will not work if it is there.
You are done and can see if it worked by pressing the preview button.
hope this helps you out, if you need further assistance, please feel free to ask. :d
