I am having a picture library which has default SharePoint column Description but my users are having more than 255 characters that needs to be uploaded for description.But SharePoint is not allowing to do so.Is there any alternate to allow 255 characters in to the description column.I am using SharePoint 2010.
It's actually quite simple. Go to list settings, click on the description column to modify it. Now change its data type to multiline text from single line of text.
Choose the number of lines based on your requirements and you are good to go. So if you have 5 lines, you should get 256*5 characters limit.
