Here's a step-by-step on how I do images with urls just for random education: (This is all done in Chrome, some steps may be different for other browsers)
Pre-step emotion_awesome: find your item in the MP. Step 1: Right click on item image, select "copy image URL" Step 2: Go to this thread (Preferably in another tab for easy access) click the "IMG" button in the posting options, (Right above the emoticons) Step 3: Paste image URL into the little box that pops up when you click IMG.
It should look like this after you're done:
Step 4: Go back to your item in the MP, select the item URL and copy that Step 5: Return to your tab with this thread and your post. Step 6: Highlight your image code, (Don't copy it, just highlight it) THEN click URL. One box will pop up, paste your URL into it.
A second box will then pop up, since you highlighted your IMG code, it should already be in that box. Click ok. Step 7: Preview your post to make sure everything is working right. :>
It should look like this in plain text:
In the thread and in your preview screen it should look like these do. (Sometimes I hover my mouse over it to make sure it's clickable and I didn't screw anything up lol) And THIS is Ruby Toadstool, it's currently 350k which is a bit pricey for this thread, but it comes with a lovely brown wig and pretty eyes. I'm surprised it's not going for more.
Skinless: 40k. This is probably not an item for everyone, but personally I love it and you can't beat that price for a detailed skin. Or lack of skin, ha.
Fortune Teller's Trade: roughly 60k. I love tarot-y occult-y stuff so this is right up my alley, but I could see it being used in many different avis. It comes with tarot cards, a crystal ball, table and really pretty purple background.
Mrs. Claws Sweater. It's a christmas sweater with a CAT. How can you go wrong? Especially when it's going for 6k
Peppermint Lollipop: A lot of you probably already own this, but if you don't, I'd snag it! It isn't just for xmas, it can be used in a variety of avis. Roughly 6k
Satin Hairbow. Oooold item but still useful if you need a touch of color at the top of the head. It comes in eight (EIGHT) colors. All for about 15k.
