How do I Select All & Submit all 100 photos on the contributor page as when I attempt that I only see three green checks on three photos & if I manually check each photo and check the submit button they do have green checks?
Sorry about your experience. Once all requirements are completed on a file it should auto green-check-select. Therefore you need to do the following checks.
Check category to make sure a category is select for each of the files.
Check to make sure there is caption for each of the files
You must have more than 5 keywording for each file.
Make sure the legal question is answered. Sometimes it is automatically selected on the default "No". Sometimes you have to select. Other times you get the impression it is automatically selected on "No" but not. In this case if no is the answer, select "Yes" then "No" to create a reset.
For each one you correct. select "Save" at the left of the page to make sure your change is saved.
If all that fails, check the "Include in submission" box at the top of the keywording column.
