well this is not actuall a problem if we say but I think this has to be corrected :)
we can share things from all over the phone directly to whatsapp from brower , photos , music , videos.... and my 80 % sharing is to share things with whatsapp .......... and whatsapp never slows down while opening a chat from hub or its app wether if I have shared many pics in a chat ........ now the problem is
we know we can attach cloud services like dropbox , box , onedrive to file manager and I have attached onedrive when I open onedrive from file manager and open a pic within it .... I only have few options like set as , share , open it in mockit ..,, I don't have the option to save it ........ so I have to share the pic directly from here to whatsapp that goes well and shared properly but when I open the chat next time from hub or app it took sometime e.g 10 second to let me able to start the chat before that it loads that pic that I have shared from cloud .... if I delete that pic from chat every thing goes fast again ........ it is disturbing when I share 10's of pics in family chat and it took few minutes to load the chat and it becomes a pain to delete every single pic from chat or let the chat load every time a new message arrive .... may be you can make it like this whenever shared from cloud whatsapp should save a copy in it for the faster acces :) well thanks for your support I hope any whatsapp dev will read and consider it :)
