If you are using a dial up Internet connection and your having troubles uploading pictures and submitting threads or replying to them try this...
Just start the thread with out any pictures then go back and upload 1 picture at a time. It also helps to edit/re-size the pictures using MS Paint or another photo editing program you may have.
You can also host your pictures on/at websites like Photobucket, Putfile, Flicker etc... and just copy and paste the direct link (URL) into your post.
As all ways if you have any questions feel free to ask.
