[Feature request]*2: force-download; other-engines

Two questions/feature requests: anything I can do to help?

(1) I'm forced to use a VPN to access google. So, I wonder if it's possible for me to easily adapt this project to other search engines? Have you done any significant work to make Bing possible or do you have any plans to?

(2) Maybe for the same reason or perhaps other reasons, google_image_search sometimes doesn't return any image results For example, I ask for 5 images, and it says it can't download any of the images; if I try again later, it downloads all five--I don't know why I get this intermittent error. Maybe it's because VPNs are not stable? But I feel that's unlikely: my VPN has been very stable, and I get the same issue on ShadowSocks.

Can we implement a feature that will force a minimum quantity of downloads to succeed for each term? Cause the script to continue working until it gets five unique pictures unless the user interrupts it? Right now, only maybe 20% of the time 5/5 images are collected.

Is there some way I can help to debug this? I'm a very novice programmer, but I can follow directions well, and I can make time.
