I recall having some annoying trouble using Google, though, and don't know if you can use those images here. Nor social media like Twitter or Facebook. Last time I used an actual photohost, it got folded into something else and all the photos went away. I don't know what all remains for those sites and services.
Sure it does. Eventually... Once you have been around long enough... (you only have 14 posts): In the lower right corner of the Enhanced* editor, there is an 'Upload a File' button. *you can set this in your profile/settings. Please Register or Log in to view the hidden image!
technically if its already uploaded then its not an up load it is a link linking Verses uploading ... i am not aware of any sites i have found where they do not allow the upload of a picture from an external device setting like a networked folder. mostly quiet the reverse you must save the picture to your hdd then upload it to the profile. this circumvents copy-write liability by the site by forcing you to breach the copy write by copying it then uploading it. cheap & effective for litigious circumstances
