We have been having the same problems in the past week.

We had one listing with 37 colour variations.

Three times we got 90%-ish of the way thru attaching the pics to the colour variations and it crashed. Very annoyed indeed.

So we left it a couple of days and came back to it again and it worked this time.

I have been away for a couple of months, now I CANNOT upload any photos! It is a farce, you click on "upload photos" and nothing happens. I even went to the trouble of speaking to some "robot" online and they gave me a number to ring, which, surprise, surprise said they were only available in office hours. When did this all change, I am seriously thinking of going over to etsy now.

It's highly unlikely to be the same issue as this thread was given it's due for long service leave.

 

Try a different browser. IE is definitely not recommended for eBay.

 

Btw I listed several items this evening through 'sell your item', plus another couple from Turbo Lister and they all worked fine.
