The picture your trying to use is on some website somewhere.
Go to the picture and right click on it and see if you can save it to your desktop.
Open a new folder, on the desktop call it ebay pics.
Take whatever pictures you took yourself, and the ones you got online and put them all in that folder.
At; Add Pictures delete all pics on the listing and start over. Browse to your desktop to find the folder and, one by one, select open them and see them on the ebay list.
Then go ahead and do the upload pics to ebay.

It is cheap and often smart to create a scheduled listing.
One advantage is that you can keep working on it before it lists.

A 10 day plus scheduled listing is an interesting strategy. For example;
Schedule for Thursday at 7 PM PST (pacific time) 10 day listing
It will end a 10 PM Sunday Eastern time, prime time for last minute ebay bidding activity.
Plus... if the buy it now is set just slightly above market value, impatient
buyers decide not to wait so long for the end and click the buy it now.
There are people who search for "newly listed items", to buy them before anyone else sees them.

With this strategy the listing is up through two weekends.
Double the exposure, and if they put it on a watch list they have the next weekend to follow up on it.

If you search for the same item you are selling and find the click box on the left for "completed listings" you can scan for the green "sold" prices to determine average market value.

It does that on mine too now for some reason but i can still see the pic on the listing.
I'd try again and contact ebay if it doesn't upload.
