Hi @BenW904
When you say you're looking to insert images/document into a file, do you mean into a campaign? If so, are you looking for this option when uploading through the Library tab of your account? Uploading through the "Images" tab of your campaign does have an insert button that inserts your uploaded image directly into your campaign. Does this button help fit your needs?
As for your folders, this is actually a defect you're experiencing. In fact there are further details we would like to collect including: what browser is the issue seen in, are there any extensions in use, and does the issue happen in an incognito session or alternate browser? In the meantime, the workarounds we suggest is to:
Locate the desired image in the main Library tab and save it on the desktop. Upload the image directly in the insert image options within the editor.
Link the desired image from an external webpage using the link button in the insert image options.
