If you are an iPhone user and an user of Windows PC then you might have encountered some issues with photo transfers from iPhone to Windows.
For a Mac user it might not be that difficult to transfer photos as both are Apple products and there are some good softwares available also which can be used for Photo Transfer.
The problem lies with Windows users. One of the problem I encountered recently is that in my Windows PC when connecting iPhone it was not showing all photos, but you can see them in iPhone.
I tried many solutions browsing through many sites including Apple and Microsoft support forums and knowledgebase along with some popular sites like wikihow.
