Could someone post pics for me?

setup an acct at photo bucket and then copy and paste the image link to the forum post

 

Like mentioned, set up a free photobucket account

www.photobucket.com

You then upload the pics you want to photobucket, creating appropriate folders if needed.  When you upload them, you have the option to re-size if you haven't already done so, I typically size to 800x600 although some of my pics I up @ 1024x768.  You can choose files individually or use the buk uploader which is pretty slick.
Once the photo is uploaded and you click on it, you'll see this page:

You're looking for the code off to the lower left:

Email and IM - for sending a link via e-mail
Direct link for - inserting pic into post, i.e. GIRS
HTML Code - for web design or using the HTML option in GIRS post
IMG Code - for inserting image into other types of forums, i.e. Reef Central

To insert into GIRS, select the picture icon

Click "yes" to allow scripted prompts

Then paste the copied code from "direct link" into the pop-up box

There are other tricks but this should get you started!
HTH!
