I am having trouble finishing an upload of product images, I have flushed the cache and uninstalled and reinstalled flash. I am using Firefox.
I browse files, select a file and hit upload and my image and it never finishes.
Can you please share a screenshot and check in your var/log directory - what exact error its gives to you ? so its helps us to troubleshoot the issue !
Which version of Magento are you using? (It seems is Magento 1 and not the latest version and neither the latest patches).
Could you check your var/system.log has any error displayed or not?
Looks like that's your issue solution:
