In case you are new to posting in forums:
Before you can post an image here in the forums, you willl need to upload your image to an image-hosting website. There are many available. For instance, you can upload images to Facebook, or someplace like Photobucket http://photobucket.com. Once you have it uploaded there, you can use it in any forum or emails etc.
When you come back here to post the image, use the image place holders [img ]type your image address here[ /img]
Example: [img ]http://i445.photobucket.com/albums/qq175/WiDoWs_WeB/Smilies/hi.gif[ /img] =
I added spaces in [img] so that the example would show, you however would not use them.
Hope this helped. If you need more help, don't be afraid to ask.
