I have seen a image like field in the account detail page , but it says to add the picture thru some social account. Is there any possibility to add a field to upload a picture and show it in the account detail page.
This requirement seems like Display Picture in Contact
In this post a complete solution is provided to add picture on any object detail page.
You only need to change logic in
DisplayImagesController class and its page as you are fetching details from social site. Some integration need to be done.
