No problem.
If you're typing your reply on this forum, you can click on the "moviewheel"icon 2 steps left of your emoticon icon. There it says insert media. Then click upload a file and upload your own file. Then select your file and insert it. Shouldn't be too hard.
Remember the maximum width of this forum is 800 pixels, so size your image down. If you want to show us full-sized images, you've got to find another way to upload your photos. Hope this helps enough.
Looking forward to your photos.
