I am greatly disappointed with the current image editor as well and have spent countless hours trying to navigate this. After speaking on the phone with HubSpot Support multiple times to walk through this issue, I learned that HubSpot previously utilized a 3rd party image editing tool called Adobe “Aviary” which has been discontinued. Thus, HubSpot users no longer have the ability to edit photos like before. An unusable croping/resizing feature has been left. I am not even able to crop images correctly. Images convert to a PNG and size up to large/unusable file sizes (as mentioned in the comments above above). Furthermore, I must also zoom out of my web browser to effectively see what I am croping.
It was suggested by HubSpot Support that I encourage my team as well as others that utilize HubSpot to comment & upvote this thread. With more upvotes, this may signal to HubSpot that this is something customers are looking into.
Currently, I am forced to utilize another editing tool that I am paying another premium for, save multiple versions of my images to meet the needs of various social media platforms on my computer and then upload these various images to Hubspot. It is my opinion that HubSpot has taken steps backward with regard to this issue and, for the premium users pay for it, I find this unacceptable. HubSpot - Please address ASAP.
