dhIMG Twitter has been updated to now include the downloading of animated files too (usually what you upload as a GIF, then gets converted on Twitter's server and shown as an MP4 file - mainly because it's much quicker to deliver and smaller in size too).

Changes in v1.2

» Images download in their original resolution
» Animated GIF/MP4 files now download
» Couple of bugs fixed

Note

I have been having a load of people contacting me to ask if the "Max Images" dropdown can be higher than 1,000. I have looked into this, however when I did a test (and set it as 2,500), it only got 1,000 - even though I've got over 7,000 media items on my account. However I will continue to look at a way around this.
