The MyCon built-in Blob Editor allows you to scroll through your current column's records without returning to the grid and presents your data primarily in two distinct views:
Text/Memo View
This view allows you full textual editing on your blob column data (or on any data on which you chose to apply the Blob Editor, see Grid Customizing for more details). This view allows you to open any external file and load it into your blob column. It also has the capability for you to type or paste any URL and download the URL's contents into your blob column. 
Keep in mind that your MySQL column might be restricted to a specific size limit depending on the column type. See Blob Memo for more details.
Picture View
This view allows you to review the picture, format and size you might have loaded into the blob column. See Blob Picture for more details.
