Q: Iphone 3gs crashes using Images APP

Hi,

I have an Iphone 3gs and I can't use properly the gallery APP. It crashes when I browse picture.

So I can't delete nor watch them on my iphone.

Plus, I can't back up because my Itunes is a 11.4 version and my last back up is dated in May, 28th. It says that "Itunes cannot back up my iphone because it can't back up it on my computer" I try to translate it in english.

I create more free space on the iphone but I solve nothing.

I already restart the device and my imac. I have followed the instruction here (sorry it is in italian) https://support.apple.com/it-it/HT203271

ios 6.1.6

Finder version 10.6.8

Itunes version 11.4

iphoto version 7.1.5

Are there any suggestions?

Many thanks
