unable to upload more than one image to a folder

Hi Thomas, 

Thanks for reaching out, I'm happy to help!

Box overwrites a file and updates the version each time you:

• edit the file using an online editor, such as Box Edit, Microsoft Office Online, or the Google editing suite)
• edit the file within your Box Sync or Box Drive folder
• use the Upload New Version button on the Web app
• upload a file into a folder that has an existing file with the exact same name in it on the Box Web app.

Its likely the last one is what's happening in your use case so you want to rename those files in your local computer before uploading them to Box.

Hope this helps! Feel free to write back in if you have any questions, and I'll help you.

Best,

thanks
