I uploaded my first content as eps and jpeg. Sales were not bad for the start. But Adobe Stock did not accept eps files accepted by istock and shutterstock, so I had to increase the resolution of the eps files for adobe stock very much. After than, i started uploading the eps and jpeg files (that i uploaded to istock and shutterstock) in zip format to adobe stock. The ones I uploaded in zip format were never sold (about two months). Adobe stock made an announcement that you do not need to upload in zip format anymore, i know. I chose the zip format because I wanted to upload my contents in the same resolution in shutter, adobe and istock. Is there anyone who can help in this matter?
