So I'm tying to download a archive that way too big... I understand that.
So I downloaded just 30 images, Worked (101MBs)
The I tried several times to get 100 images. That Dies with some failed to zip error. And I was running out of ram.
Restart with clean run of FF, tried to get 50 images. FF used about 300MB (of RAM), and fails during the start of the zip process with (NS_Out of Memory). FF isn't using anymore ram past downloading the last pic. System isn't out of ram..., and FF's only using 770MB overall
Tried both 100, and 50; 4 times each,
Go back to 30 images per zip, and it instantly makes a zip
grab the next 30, it instantly get 20, and starts downloading the 50th. also works
Those two archives are only 172MB total, which is 60 images and at double ram usage is only 344MB which should be well under the 800MB FF limit.
The four archives (30,30,30,10) that represent the 100 images originally tried, total up to just 304MB which at double ram is 608MB and still well under the 800MB FF limit.
It is downloading all the images fine, its just the JSZIP that's dying. I would much rather have the script download all 600 images (and save), and then zip (or RAR/.7/.ace) them by hand; As downloading 20 little 30-image zipfiles, is annoying.
