so...from my end here it looks like pic sizing has a lot to do with it.
the pic from the acer laptop is 450kb and it posted fine. i dont know the size of the original pic from my iphone 5 because i cant seem to find that info, but i was unable to post it in its original size. however, after i emailed it to myself from my phone, resizing it to 296kb in that email, and then re-saving it back to my iphone as the new 296kb size, i was able to post it from my phone. zoiks!
for what its worth, i have heard from others that posting pics directly to the asf is troublesome, especially from iphones.
my $.02...i always prefer to host my vw pics on thesamba.com and then i can post them from there to any site i like. its a little extra work, but it's well worth it imho because then we're not dealing with dead pic links (like from photobucket, flickr, here or other hosting sites). i've been doing it that way for many years and i've never had a problem with hosting or posting pics!
geoff..do you get an error message when you try to post pics? maybe you need a pic resizing app for your new phone? maybe the admins can offer more info?
