Yes, I am fully aware of that function. I tried 0 and 0, but still when saved it's coming up 10... so thought you'd want to know. The include_images.asp file makes a reference to the "hspace=5" -- but just for kicks and giggles I took that out ONLY, but the 5 still defaults, so I added it back and left the file UNCHANGED.
Try this to replicate the spacing...
- Insert the image
- Save/Update
- Double click on the image
- Do you see 10 and 10 in the area you reference above?
