FLDisneyFan - The way I upload is first I resize my pictures on my PC using PIXResizer, a free program you can download from the internet. I resize my pics to 1024x768. The program then asks you where to save the pic, I use the Desktop if I am doing one pic.
I use Photobucket to upload my pics. I create albums of each day of my trip to upload to. You can also upload mulptiple pics at the same time.
You select the image you want put in your thread by rolling the mouse over the picture. A drop down menu appears and select IMG code. It should say "copied". Then go back to your thread and right click and select paste. The code should appear in your message.
This may sound long, but with practice it is easy. Let me know if you need more help.
