1) You can set hot linking for certain URL addresses if you so choose. Ex: I have hotlinking disabled on my website but allow certain places to hotlink. I have listed certain urls as allowed so they can access certain images. So people could sign up to link to your site, you ALLOW them. All others trying to pull in the image would be blocked. Yup...I do it in cPanel.
If you do not place them in an allowed list then YES, they would be blocked. Please note that if you allow hotlinking on your site that YOUR BANDWIDTH will be used to load images on the other site. Your site resources will be used to make their site better. Most sites that do that eventually have one of two things happen: either they collapse from too much drain or they go paid subscription to support the image drain. One of my favorite free gif sites failed because of drag.
2) Code. Well, each image has a code box on its own separate page. I use a pared down code box all over SAMISITE.
You can see it in use on this page. If you want the code, I used the
Select and Copy form element script- By Dynamicdrive.com, with my usual CSB adjustments and instructions. (the samples on that page work fine in IE but firefox will no longer do the rollover sound.
)
As to Turtle, I am glad he has no more medical worries..what next is no longer an issue for him. He is at peace. I am saddened for his family at the loss of someone so very special. I am saddened by the thought that others will not have the chance to know how special he was. And I feel his loss intently on a personal basis. He was such a kind gentleman that got such joy from helping people even as his own health deteriorated. I loved our interaction and considered him my Guru. Since arriving at the Trellix Cafe, he has had my back. Coaching, encouraging, correcting and pointing me to new better things, new ideas and all the while being positive that I could do it! I always felt like I was learning to walk the high wire and he was my mentor and safety net. Now I feel unbalanced. Up too high with no one to catch me if I fall. I miss the security of knowing he would check in on me. I will miss his posts. I will miss our off-forum communication. Maybe he made it to the rainbow bridge to meet his special pet.
