The Ele Toldot at Leo Baeck Inst is a goldmine of information, with a page listing parents, spouses, children and documentation for every identified individual (mostly from the gravestones in Frankfurt cemeteries and vital records).
I go to http://www.lbi.org/digibaeck/results/?qtype=pid&term=258967
At the very bottom, I click on View Object
Then on the Copyrights page I click on the lower right corner on Continue
On the next page, on the left side, there is a menu and I click on the little + next to Part C. Hauptteil (Personalregister)
That gives a list of date ranges for the profile pages for each person buried in the Frankfurt cemetery and other family members.
Click on one of the date ranges and you will get the Copyrights screen in the window to the right. Click Continue in the lower right corner and then it will download the pdf of that file
You can scroll up and down using the bar on the right side.
When i click in the lower right corner of that screen, I get a menu of options to zoom in and out and save and print.
I use screen shot (see Apple-Shift-4 on a Mac or http://www.awesomescreenshot.com on a PC) to take a shot of the image and use it to upload as a photo to the profile page of the person on Geni.
I hope this helps. If you need any more help figuring out how to use it, please contact me on Geni at Randy Schoenberg or send me an e-mail at randols@bslaw.net.
