Google Nexus 5 - Attaching files to email or craiglist on Chrome

[gera815]

i have a problem here. I am coming from a Galaxy S4 and i always attached images on my emails or on craiglist when i clicked on attachments. When clicking on attachments it gave me the choose an action menu and i clicked gallery since all my images were there. On my Nexus 5 i click attachments to insert a picture and it also gives me choose an action but it only gives me Camera to take a picture, Camcorder to record a video or Documents but no gallery or anything. Can u help me out
