If you have the photos stored on photobucket, you didn't post them the correct way anyway - you don't want to treat them as attachments. Photobucket will resize the images to a manageable size too.
I'll write up a slightly more detailed tutorial on how to do that sometime when I've the time. It's rather easy - lots of importers are showing their photos which are actually on photobucket (so in other words,
you don't have to be good at computers do know how to do it <---- I hear that excuse ALL the time!).
What you want to do is focus on the section under each picture in photobucket where it says "Direct Link":
Thanks
Copy that information by clicking on it (it'll momentarily show a small balloon saying "Copied").
Next, go into your post here in simplydiscus and click on the "insert image" icon.
It'll bring up a little dialog box, you want to pass the info into here. For those who do not know their keyboard shortcuts, you want to hold the CTRL key down and then press the V key. Click the OKAY button, and you're all set (you'll see some odd code appear in your message, but when you're done with your post, the image will show up - you can also preview your post).
Hope that helps.
