Error 5000 can not upload pic or anything else, try several times...
Hi, welcome to the community!

Mouse over your name at the right top, click on the "Upload pictures" link in the drop down menu. Drag the images onto the square area you can see. Make sure you have Java installed in your computer.
However, if you're on a Mac, the drag & drop image upload won't work.
If the file is too big it will give you an error too, so make sure it's the right size ..
