Can't find jpegs on Scribd

[ackern]

Not sure this is a bug exactly so sorry if mis-posted. DTA isn't finding all the jpg files on Scribd pages like this one because the pages load extremely outrageously slowly which I am guessing is intentional on the part of Scribd (my speed is excellent on all other websites). No page image within the doc loads until you scroll to it and wait there for at least 5 seconds and then the jpg takes 15-60 seconds to load. The documents I am talking about are all scans of 50 year-old magazines i.e. not things people wrote on computers.

So for DTA to work you must spend 5 to 20 minutes slowly manually scrolling through the document. If you don't do that DTA won't find the all the jpgs.

Same thing happens in Firefox Tools > Page Info > Media and in fact you can download all the jpgs there so in this case DTA isn't needed at all. So my question is does DTA have a way to get around the 5~20 minutes of scrolling?
