HELP iOS6 causing iPad to do a full Restore

[leonharris]

Somebody please help:

i just updated to iOS6 on my gilfriend's iPad 2.

then i looked at my iTunes to see it says "full restore needed".

so now i have lost ALL the photos of her 6 month old niece (not to mention all the other photos she had on there).

i have not clicked the full restore yet.

is there ANY WAY POSSIBLE TO REVERT TO iOS5 AND NOT LOSE ALL HER PICTURES?

any help much appreciated.

thanks in advance,
Leon
