Also your upload limit will be refreshed after reviewing of all the files you submitted is complete.
If your upload limit has not been changed, the reason must be one of followings:
1) You currently do not have over 500 images. Please increase your portfolio and then apply again.
2) Your portfolio couldn’t be approved our review to increase your maximum upload limit.
As you keep on uploading your images, the system will raise your limit. Please cope with current upload limit for now.
3) You sent a URL of your portfolio which we cannot review your images such as Facebook, your own homepage nor your portfolio of PIXTA.
Please apply again with your portfolio which you currently sell your images on other stock library.
If your limit is raised but not satisfied, please don't be worried.
