Why can't I upload pictures onto Craigslist from my iPhone 5c?

It's not only Craigslist, I can't upload any pictures into many websites from my picture roll. My phone looks like it's uploading the pictures but then it just sits there for ten minutes and eventually I get a notification that says that my connection timed out.

Another thing: I use LTE network for my phone since I do not have Wi-Fi.

  • Why doesn't it let me upload pictures? (FB/IPHONE/IPAD2)? Its telling me "upload failed" ever since last week. I can't upload pics, to a certain album, on my facebook, from my pictures on ipad/iphone. Grr, what happened! -.
  • Why can't I upload pictures to facebook from my iphone or computer anymore? I have an iphone and a macbook pro. I have been able to upload pictures onto my facebook from my phone or computer fine until now. All of a sudden it doesn't work. I tried everything. I updated adobe software. I made sure my privacy settings on my iphone allow photos. I tried uploading different photos. I tried computer and my phone. So it must be my facebook.
  • Why can't I upload pictures from my iphone to my laptop? Usually when i plug in my iphone to my laptop, something pops up asking if i want to import my photos. Now itunes is just popping up and not the import photos thing. Sorry if this makes no sense i don't know the correct terms lol.
  • Why can't I load pictures onto my iphoto anymore? I have a mac by the way so last week i plugged my friend's iphone to my iphoto to transfer some pictures. I forgot to eject her phone and i just removed the chord from my computer and it says her device was still attached. Now I can't load pictures from my phone to my iphoto. My iphone doesn't show up on the list of devices connected on iphoto. What should I do? What should/can I do to connect my iphone to my iphoto so that I can load my pictures again?
