Did you see my post on that other forum about copying images in forum posts?
"The image has to be stored in a linkable location. This website has to be able to create a link to the image's location. Such as, Flickr, Photobucket, a web site, etc. I don't have a Flickr, Photobucket, etc account, so I upload (store) my images to my Facebook account and copy from there to create a link."
Do you have a linkable location you can store photos? I've had 100% success since I started uploading images to Facebook and then copying the image (right-button mouse click, Copy Image) from Facebook and then pasting (Ctrl + V) the image here in the forum post.
Of course, the Card ID forum will always work, too.
Someday my cards may double in value and then be worth half of what I paid for them.
