Default can't upload attachments like pictures

Can someone explain to me what I'm doing wrong when trying to upload a screen shot I click on attachments my phone is already plugged into my computer but when I click choose file nothing happens and if I try to upload from Dropbox or drive or mega I get it saying sorry not a valid image type when it's a jpg and only 156 kbs can't figure it out and my phone is the lg g2 vs980 computer running Windows 7 and I'm using boat browser on my phone to go to xda
Thanks in advance for any help
