The way I put pictures on the forum are these steps:
1. Copy pic from camera to pc.
2. reduce MB to 100 or less (usually between 85MB and 98MB)
3. copy reduced sized picture to a picture album in my profile on the forum. Click on your user ID at the top of the page to access your albums and other things.
4. Open the picture and copy the bottom of the two URLs.
5. Switch to the thread window you are replying to and paste the link there.
This felt like a pain when I first started but now I do it quickly. I just got used to the steps.
This may not be the easiest way or the best way either but it works. If you want to try this and have questions please ask. My "steps" may not be clear.
