I kept the following note to remind me how to paste picture on forum text.
1. upload the target picture onto Kit Maker Network photo album.(the Kit Maker Newwork need another login)
2. view the target picture. A "Linked Thumbnail:" column with the picture ip URL shown at buttom.
3. Click the ICON at the end of Linked Thumbnail to extend 2 more ip information : HTML code and Direct Link.
Now, test to see result with these 3 ip URL.
a. Copy and paste Direct Link of Album photo :
result : failed.
b. Copy and paste HTML code of Album photo:
result : OK and picture is large.
c. Copy and paste Linked Thumbnail of Album photo:
result : OK but picture is small and need to mouse click at the picture to view the large image.
