I post links all the time. What would be the issue with posting legitimate links?
Cumer, you have A LOT of stamps in your post, and many are partially covered by approval cards. You will get better help and engagement from folks on the forum if you pick just a few stamps at a time.
Select 3 stamps that you are most concerned about, and scan them on a scanner, 1 at a time. Minimum should be 300 dpi, but 600 and 1200 DPI are better. Photos are not as good. This method will provide large, crisp, sharp images for viewers.
Before uploading the images, make sure to reduce the size of the photos to 200K using the "Free Image Optimizer." A link to the image optimizer can be found on the page where you post messages- see screen shot below. If the image is small, click on it and you'll see a very large version.
Good luck- we're all here to help.
