Rated 1 out of 5 stars
This failed on most images I tried to grab.
I recommend you try this:
1) Go to Flickriver.com and find what you were trying to grab (you can view all images by a user or group, and narrow by tags, etc. It's very specific or general as you want it.)
2) Go to the drop down that says "Photo Size" and select 'Show Large Size'.
3) You'll now have all images, in their max resolution in one tab.
4) Use 'Save Images' addon: https://addons.mozilla.org/en-US/firefox/addon/3404/ by right clicking and selecting 'Save Images From Current Tab'.
I gave this a '1' only because after my first several attempts failed to produce ANY result, I just removed it.
