Help! How do I add another picture to my listed item.Must do it tonight.

[Conserve]

I have listed an item for auction. I've been asked to provide a picture of the back view.
I have googled as I dont know how to do this.

It says go to 'Revise your Item' in My Ebay and 'replace photo'.

I Cant Find 'Revise your Item' anywhere!

I have asked for their email address to do it that way but no reply yet.

Please can someone give me step by step instructions on how to do this.
I want to be as helpful as I can so it gets sold and I get good feedback.

Thank you. I'm exhausted - this frustration is so exhausting!

If you add a pic to photobucket and then you add it to the eBay auction by copy and pasting the HTML code in the HTML bit of your description.
Hope that makes sense!

Thank you horsemadgal for your reply.
I have got the pictures ready on my computer in 'my pictures - ebay'. I have already put pics on when I first created the listing. I will be able to put these extra ones on when I can find the page where it will let me Revise My Listing but I cant find it.
Not sure what a photobucket is or HTML

Sorry photobucket here

Should be a 'revise my item' bit when you go into your auction.
Click that and scroll down until you see 'describe the item you are selling'
Under that there are 2 tabs standard and HTML.
Click the HTML tab and then you can paste the code from photobucket underneath all the weird computer talk stuff.

Thanks for your help!
Bed now.
