Sorry to add to the grief, but having the same problems here ... trying to populate a TR with images.

Click on the 'landscape' icon and it takes at least a minute for the upload page [sometimes] to refresh. Managed eventually to upload one using the 'traditional' drag and drop from my desktop, but the 2nd attempt just failed.

It seems from one screen I saw that one is now also supposed to upload from a FT album. Hmmm. I did that (TR 19f CPT) but the photo order was scrambled in the process. And when I tried to upload from the album, it only showed a dozen or so of the 70-odd images.

Seriously borked, it seems!

PS: Tried again. The image downloader seems to be trying to 'write' the 3rd option on the pop-up screen which activates the Drag and Drop, but stalls very early on according to my Mac progress bar. Curiously, I've managed a Drag and Drop with the first image without that 3rd option, but again it just won't do the next one.
