Hey guys- I've added a new feature that will make it much easier for you to add a picture with your post. Whenever you create a new topic or quote/reply to a post (not via Quick Reply), you will see a button that says "Upload picture".
Browse for the photo you want to upload on your computer, then click the "send". Once uploaded, you would click the "insert picture" link to automatically paste the link to the picture in your post.
Let me know if you have any questions or run into any problem with this!
