FIRSTLY - apologies if this has been tackled previously - I can not find a solution currently on here!
When using SFTP - it appears to be a different set-up to that of FTP in terms of sending images.
When using FTP - using the save and upload facility when the caption window is open (and not Apple U) the file is sent to the previously used server location - hence SAVE & UPLOAD.
However, when the previous destination was an SFTP one, when captioning saving and uploading and going to the next image using the Save and Upload button, it resorts to an FTP connection.
I have looked in prefs to see if I can find a solution but I see nothing.
Can one send images to a server using the Save & Upload command without using Apple U?
