I tried uploading a photo earlier today, just to see what would happen/if it would work. Whilst on the screen that you've taken a screenshot of in the following post, there were three little bars in the top righthand corner symbolizing that it was processing my request, but it never completed the processing and never uploaded my photo.
I was also getting a symbol in my browser, whilst on the 'upload media page', that was telling me 'Flashplayer was out of date', so had been blocked. After updating the adobe flashplayer, I tried uploading the same image I'd being trying previously, and it worked, really quickly.
I thought I'd share this, just in case it could help others with uplaoding media.
Yes,that does work. for me.
I installed Adobe Crashplayer against my better judgement and was able to upload an image, Now that issue has been resolved,but the uninstall of Crashplayer will be my next step as I don't use or trust it one single bit. That spells the end of my uploading days here.
