After you create the account think about what kind of folders & subfolders you want (like you probably already do with your MP3s). For example, I have one folder of all Scion ‘pics I use in posts like this. Then I have subfolders for particular shows, club stuff, my box at different stages, etc. It’s important to give a little thought first because if you decide to rearrange them later you’ll screw up the links for any posts you already used them in. (So they’ll turn into those annoying red Xs or display that “can’t find the ‘pic” message.) And if you just dump them all in one huge folder you may have to sift through a lot of pages looking for one later.
After you upload your ‘pics you will see three different links below each one. Click on the last one “IMG Code.” It should highlight the entire line next to it. Right click and select “Copy.” When you want to post that ‘pic just right click and select “Paste” wherever you want it to appear in your message. Be sure to preview your post before you submit it. You should now see your ‘pic.
