WHY WOH'T MY PICTURES UPLOAD?

Possibly over the limit of bytes allowed. There is only so much bandwidth the site will allow you to use, one at a time also you can only upload one image in a dialogue box, when it says choose file choose only one, try that

Same issue here and it isn't 10MB, which is the maximum allowed for each photo. They really need to update whatever system they use. It's rediculous.

I just ran into this issue as well - 9 years from when this issue was first posted and no update?

I just had the same issue and got it to work. Open the photo. In the upper right hand corner open the selections drop down and select resize. Make sure you select Jpeg when saving them after selecting the size you want. If it doesn't work resize even lower and do one by one clicking inside the folder you saved them in to verify you can view them.
