How long does it generally take to download an archive?

[Aqua]

Hey everyone, brand new to the site here, and just wanted to say I love it

I have a question though. Does anyone know how long it typically takes to create an entire archive in order to download it? I'm sure it varies by the size of the image gallery, but just an approximation based on numbers would be extraordinarily helpful.

For example, I'm trying to download someone's entire album for the first time. There are about 750 pictures in the archive, and when I clicked on "download album", it's been telling me to "Please wait. Archive is being created" for the past 3 hours. Just wondering if I should let it idle if it's actually doing so, or if there's been a problem and it's actually not doing anything at all.

Any feedback on how long it takes to create an archive from a picture album based on estimates would be appreciated. (i.e: 100 pictures = 1 hour).

Thank you!
