5 mb, it's not that big. Uploading "small" files is not a good solution. In stock photography, we have to upload large files ( particularly for commercial use).
 I still have the same uploading problem with alamy and the problem is only with them. No problem with other stock libraries despite of the covid 19 crisis ( these libraries are located in countries that have been severely affected by the epidemic).

The upload problem has started beginnning of march. No lockdown due to covid 19 at this time. So I complained on the Alamy forum and soon uploading was possible and the QC time was fast, very fast. But after something like 2 weeks the upload problem was there again. It was during the last 10 days of march. I have written to the alamy contributors team several times but their answers were irrelevant. Then they stopped answering beginning of april. And the upload problem remains.
